実験手順

A mixture of 1.66 parts of 2-chloro-3-pyridinecarbonitrile, 4.28 parts of cis-4-amino-N-[1-(2-aminoethyl)-3-methoxy-4-piperidinyl]-5-chloro-2-methoxybenzamide, 1.3 parts of sodium carbonate and 22.5 parts of N,N-dimethylacetamide was stirred for 20 hours at 70° C. The reaction mixture was taken up in dichloromethane. The organic layer 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 (95:5 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 1.19 parts (21.6%) of cis-4-amino-5-chloro-N-[1-[2-[(3-cyano-2-pyridinyl)amino]ethyl]-3-methoxy-4-piperidinyl]-2-methoxybenzamide; mp. 134.0° C. (compound 32).
