Procedure
A mixture of 40 parts of ethanimidamide hydrochloride, 20 parts of cis-N-{4-[4-{4-[2-(2,4-dichlorophenyl)-2-(1H-imidazol-1-ylmethyl)-1,3-dioxolan-4-ylmethoxy]phenyl}-1-piperazinyl]phenyl}hydrazinecarboxamide, 40 parts of sodium acetate and 90 parts of N,N-dimethylformamide is stirred and heated for 4 hours at 130° C. The reaction mixture is cooled and 100 parts of water are added. The precipitated product is filtered off, washed with water and with 2-propanol, and crystallized from 1-butanol, yielding 9 parts (44%) of cis-4-{4-[4-[2-(2,4-dichlorophenyl)-2-(1H-imidazol-1-ylmethyl)-1,3-dioxolan-4-ylmethoxy]phenyl}-1-piperazinyl]phenyl}-2,4-dihydro-5-methyl-3H-1,2,4-triazol-3-one 2-propanolate (2:1); mp. 295.7° C.
