Diethylamine → HCID 14054340, compound

Participants

Reaction Steps

The reaction is carried out as in Example 1, starting with 4-(4-chlorophenyl)benzo[b]thiophene-6-carboxylic acid (4.67 g) in toluene (45 cc) and thionyl chloride (3.6 cc) and then triethylamine (6.9 cc) and diethylamine (1.7 cc) in toluene (45 cc). After chromatography of the residue using a cyclohexane:ethyl acetate (90:10 by volume) mixture as the eluent, a residue is obtained, which is stirred for 2 hours in 40°-60° petroleum spirit. After filtering and drying, N,N-diethyl-4-(4-chlorophenyl)benzo[b]thiophene-6-carboxamide (1.07 g), m.p. 135° C., is obtained.
