The resulting compounds 141 were mixed either with thionyl chloride (yielding 115, 120 or 126–128), DAST (yielding 118, 121 or 130), acetic anhydride and dimethylaminopyridine (yielding 132) or trimethylsilyl bromide (yielding 116, also obtained from the previously synthesised silyl ether lactam...
However the method disclosed in patent literature 1 is problematic because catalytic reduction is carried out in the presence of ammonia or acetic anhydride, acetic acid, etc., and hydrogenation is conducted at a high pressure of 20 atm or more, and thus limitations are imposed on selecting the...
PROBLEM TO BE SOLVED: To obtain 4-acetylamino-3-methylbenzoic acid as an intermediate for 1H-indazole-5-carboxylic acid, by reducing 3-methyl-4-nitrobenzoic acid and reacting the reduced compound with acetic anhydride in an organic solvent.ISEKI EIICHI...
