Reaction Steps
To a stirred solution of 4 parts of cis-4-amino-5-chloro-N-[1-[3-(4-fluorophenoxy)propyl]-3-methoxy-4-piperidinyl]-2-methoxybenzamide in 64 parts of ethanol was added a solution of 1 part of (Z)-2-butenedioic acid in 16 parts of ethanol and the product was allowed to crystallize. It is filtered off and dried, yielding 4.8 parts (92%) of cis-4-amino-5-chloro-N-[1-[3-(4-fluorophenoxy)propyl]-3-methoxy-4-piperidinyl]-2-methoxybenzamide (Z)-2-butenedioate (1:1); mp. 200.3° C. (compound 240).
