| abstract | NEW MATERIAL:The compound of formula I [R 1 is H or 1W4C alkyl; R 2 is H, 1W6C alkyl, (substituted) phenyl, or (substituted) benzoyl], its salt or its ester. n EXAMPLE: 4-Methoxy-5-phenyl-2-thiopheneacetic acid. n USE: Pharmaceuticals or intermediates of pharmaceuticals and agricultural chemicals. PRCESS:The compound of formula I can be prepared e.g. by condensing the compound of formula II (R 4 is 1W4C alkyl) preferably in a solvent in the presence of a base such as metal amide when R 2 is H, alkyl or (substituted) phenyl, or in the presence of a base such as an alkali metal alkoxide when R 2 is (substituted) benzoyl, and hydrolyzing the resultant compound of formula III (R 1 is H) in a solvent in the presence of an alkali metal oxide. n COPYRIGHT: (C)1984,JPO&Japio |
