(VII):

(I) The compounds of formula (I) can be converted to additional compounds of formula (I) using standard procedures. For example, compounds of formula (I) wherein the group Ar 1 is substituted by bromine, can be converted to compounds of formula (I) wherein the group Ar 1 is substituted by -CH = CH-R 20 wherein Y is CH = CH and R20 is a group -NR6C (0) NR7-R8, -C (0) NR7R8, -NR7R8, -C (0) OR9, -NR10C (0) NRX1-Z-R12 or -C (0) NRX1- Z-R12 wherein Rs, R7, R8, R9, R10, R11 and R12 are as defined in formula (I) when reacting with compounds of formula (XV):
H2C = CH- R2 (XV)
where R20 is as defined above, using Heck chemistry. For example, compounds of formula (I) wherein Ar 1 is naphthyl substituted by bromine or iodine, can be treated with palladium catalyst and a compound of formula
(XV) in a suitable solvent at elevated temperature. If desired, the palladium catalyst can be formed in situ. The resulting compounds of formula (I) prepared using the above chemistry can be converted to additional compounds of formula (I) by reduction of the double bond of the group -CH = CH-R20. This can be carried out under standard hydrogenation conditions, for example using palladium on activated carbon. Other methods for transforming compounds of formula (I) into additional compounds of formula (I) will be apparent to those familiar in the art. For example, compounds of formula (I) containing a group -YC (0) OR9 wherein R1 is methyl, can be converted to compounds of formula (I) having a -YC (0) NHMe group by treating them with methylamine in methanol at elevated temperature. Preferably, the reaction is carried out at approximately 100 ° C in a sealed container. The same transformation can be carried out using trimethylaluminium and methylamine hydrochloride in toluene at reduced temperature, for example at about 0 ° C. The compounds of formula (I) which contain a group -Y-C (0) OR 9 can also be converted to the corresponding carboxylic acids by hydrolysis. Preferred conditions include treatment with lithium hydroxide in a suitable solvent system, for example in water / THF at room temperature. The compounds of formula (I) which contain a group -Y-C (0) OH can also be converted to compounds of formula
(I) having a group -Y-C (0) NR7R8 by reacting with the appropriate amine. For example, amines of the formula HNR7R8 can be reacted in a suitable solvent such as DMF in the presence of 1-hydroxybenzotriazole and l-ethyl-3- (3'-dimethylaminopropyl) -carbodiimide. Compounds of formula (I) containing a -Y-C (0) R7R8 group can be converted to compounds of formula (I) having a -Y-NR7R8 group by treating them with a borane / tetrahydrofuran complex. An alternative synthesis of compounds of formula
(II) is via (a) selective reduction of compounds of formula (XVI): (? V?:
wherein R3, R4, X and Ar1 are as defined in formula (I). Suitable reducing agents include sodium borohydride or zinc borohydride (Tetrahedron Lett., (1985), 26, 4463). The triple bond in the compounds of formula (XVI) can also be reduced to form compounds of formula
(III) using conventional procedures, for example hydrogenation using a palladium catalyst in an inert solvent such as ethyl acetate. The compounds of formula (XII) can be prepared by reacting a compound of formula (VIII) as defined above with a compound of formula (VII) as defined above. The intermediates described above are prepared as described above, are commercially available, or can be conveniently prepared using known techniques. Certain intermediate compounds are novel and form a further aspect of the invention. It will be appreciated by those familiar with the art that in the process described above, the functional groups of the intermediate compounds do not need to be protected by protecting groups. The functional groups which it is desirable to protect include hydroxy, amino and carboxylic acid. Suitable protecting groups for hydroxy include organosilyl groups (for example tert-butyldimethylsilyl, tert-butyldiphenylsilyl or trimethylsilyl), benzyl and tetrahydropyranyl. Suitable protecting groups for amino include tert-butoxycarbonyl or benzyloxycarbonyl. Suitable protecting groups for carboxylic acid include alkyl or benzyl esters. The protection and deprotection of functional groups can be carried out before or after a reaction step.

Groups in Organic Synthesis ", 2nd edition, T. W. Greene &P. G.
