実験手順

To a stirred solution of 3.00 parts of 1-(4-chloro-1-oxobutyl)pyrrolidine in 67.5 parts of N,N-dimethylformamide were added 1.93 parts of trans-4-amino-5-chloro-N-(3-hydroxy-4-piperidinyl)-2-methoxybenzamide and 1.5 parts of N,N-diethylethanamine and the whole was stirred for 18 hours at 70° C. The reaction mixture was evaporated and the residue was taken up in a sodium carbonate solution in water. The product was extracted with trichloromethane. The extract was washed with water, dried, filtered and evaporated. The residue was purified by column chromatography over silica gel using a mixture of trichloromethane and methanol, saturated with ammonia, (90:10 by volume) as eluent. The pure fractions were collected and the eluent was evaporated. The residue was crystallized from acetonitrile. The product was filtered off and dried, yielding 2.1 parts (47.8%) of trans-4-amino-5-chloro-N-[3-hydroxy-1-[4-oxo-4-(1-pyrrolidinyl)butyl]-4-piperidinyl]-2-methoxybenzamide; mp. 174.7° C. (compound 15).
