Den ovenfor nævnte intramolekylære kondensation kan udføres på konventionel måde. Omsætningen er exoterm. Den kan f.eks. udføres i et vandfrit medium under anvendelse af en ether såsom dimethoxy-ethan eller et carbonhydrid såsom toluen som opløsningsmiddel eller et 5 andet opløsningsmiddel, der er inert under reaktionsbetingelserne. Reaktionstemperaturen er ikke kritisk og kan ligge mellem ca. 0°C og 100°C. Da reaktionen er exoterm startes reaktionen hensigtsmæssigt ved stuetemperatur, og reaktionstemperaturen lades stige jævnt.The above mentioned intramolecular condensation can be carried out in conventional manner. The turnover is exothermic. It can e.g. is carried out in an anhydrous medium using an ether such as dimethoxyethane or a hydrocarbon such as toluene as the solvent or another solvent which is inert under the reaction conditions. The reaction temperature is not critical and can range from approx. 0 ° C and 100 ° C. As the reaction is exothermic, the reaction is conveniently started at room temperature and the reaction temperature is allowed to rise evenly.

Omsætningen udføres hensigtsmæssigt i nærværelse af et syrebindende 10 middel såsom natriumhydrid, natriumamid eller et natriumalkoholat, f.eks. natriumethylat.The reaction is conveniently carried out in the presence of an acid-binding agent such as sodium hydride, sodium amide or sodium alcoholate, e.g. sodium.

Den intramolekylære kondensation kan også udføres i et vandigt/or-ganisk tofasesystem i nærværelse af en uorganisk base, f.eks. natriumhydroxid, og eventuelt en katalytisk mængde af en faseovergangs-15 katalysator. Den organiske fase kan omfatte et hvilket som helst hensigtsmæssigt inert med vand ikke-blandbart opløsningsmiddel såsom carbonhydri der eller halogenerede carbonhydrider, f.eks. xylen, toluen, o-dichlorbenzen eller dichlormethan. Hensigtsmæssige faseovergangskatalysatorer er kvaternære ammoniumforbindelser såsom 20 benzyltrimethylammoniumbromid, kvaternære phosphoniumforbindelser såsom benzyltriphenylphosphoniumchlorid og krone-ethere såsom 1S-krone-6.The intramolecular condensation may also be carried out in an aqueous / organic two-phase system in the presence of an inorganic base, e.g. sodium hydroxide, and optionally a catalytic amount of a phase transition catalyst. The organic phase may comprise any convenient inert with water immiscible solvent such as hydrocarbons or halogenated hydrocarbons, e.g. xylene, toluene, o-dichlorobenzene or dichloromethane. Suitable phase transition catalysts are quaternary ammonium compounds such as benzyltrimethylammonium bromide, quaternary phosphonium compounds such as benzyltriphenylphosphonium chloride and crown ethers such as 1S-crown-6.

2-Chlorethyl 2-(2/6-dimethylphenyl)hydrazincarboxylat.2-Chlorethyl 2- (2/6-dimethylphenyl) hydrazine carboxylate.

En blanding af 17,7 g (0,1 mol) 2,6-dimethylphenylhydrazinhydro-chlorid, 21,2 g (0,2 mol) natriumcarbonat i 50. ml vand og 50 ml xylen 5 omrøres i 30 minutter ved stuetemperatur og afkøles derefter til 5°C. Derefter tilsættes i løbet af en periode på 1 time 14,3 g (0,1 mol) chlormyresyre-2-chlorethylester, idet temperaturen holdes ved 5°C. Blandingen omrøres ved 5°C i yderligere 1 time, og ved afslutningen af denne tilsættes 100 ml vand, og det således vundne bundfald 10 frafiltreres, vaskes med vand og tørres. Yderligere oparbejdning foregår som i eksempel Ib.A mixture of 17.7 g (0.1 mole) of 2,6-dimethylphenylhydrazine hydrochloride, 21.2 g (0.2 mole) of sodium carbonate in 50 ml of water and 50 ml of xylene 5 is stirred for 30 minutes at room temperature and cooled. then to 5 ° C. Then, over a 1 hour period, 14.3 g (0.1 mole) of chloromyric acid 2-chloroethyl ester are added, keeping the temperature at 5 ° C. The mixture is stirred at 5 ° C for a further 1 hour and at the end of it 100 ml of water is added and the precipitate thus obtained is filtered off, washed with water and dried. Further work-up takes place as in Example Ib.

På analog måde som beskrevet i ovenstående eksempel 1 og 2 fremstilles følgende forbindelser med formlen I.By analogy as described in Examples 1 and 2 above, the following compounds of formula I are prepared.
