Abstract
NEW MATERIAL:A propionamide derivative of formula I: (A is O or S; X is N or CH).
EXAMPLE: 2-[10,11-Dihydrodibenzo [b,f] thiepin-2-yl]-propionamide.
USE: Anti-inflammatory drugs.
PROCESS: A compound of formula III or its reactive derivative is reacted with NH3 in the presence of a condensing agent, e.g. dicyclohexylcarbodiimide, etc. in an inert solvent, e.g. methylene chloride, etc. to give the compound of formula I. An acid halide, obtained by reacting the compound of formula III with a halogenating agent, e.g. thionyl chloride, phosphorus pentachloride, or a mixed acid anhydride, obtained by reacting with ethyl chloroformate, etc. may be cited as the reactive derivative.
