実験手順

To a stirred solution of 4.04 parts of cis-1-[4-(4-amino-3-methoxy-1-piperidinyl)-1-oxobutyl]pyrrolidine in 225 parts of trichloromethane was added a solution of 4.15 parts of 3-chloro-5-ethyl-6-hydroxy-2-methoxybenzoyl chloride in trichloromethane. After stirring for 15 minutes at room temperature, 1.9 parts of N,N-diethylethanamine were added and the whole was stirred overnight at room temperature. The reaction mixture was washed with water, saturated with ammonia and twice 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 2,2'-oxybispropane. The product was filtered off and dried, yielding 5.2 parts (71.9%) of cis-3-chloro-5-ethyl-6-hydroxy-2-methoxy-N-[3-methoxy-1-[4-oxo-4-(1-pyrrolidinyl)butyl]-4-piperidinyl]benzamide; mp. 90.8° C. (compound 67).
