Versuchsvorschrift
The reaction is carried out as in Example 1, starting with 4-(4-methoxyphenyl)benzo[b]thiophene-6-carboxylic acid (2.9 g) in toluene (30 cc) and thionyl chloride (2.3 cc) and triethylamine (4.3 cc) and diethylamine (1.1 cc) in anhydrous toluene (30 cc). After chromatography of the residue on silica gel using a cyclohexane:ethyl acetate (80:20 by volume) mixture as the eluent and recrystallization in isopropyl ether, N,N-diethyl-4-(4-methoxyphenyl)benzo[b]thiophene-6-carboxamide (1.12 g), m.p. 88° C., is isolated.
