Participants

Reaction Steps

A mixture of 20 parts of intermediate 17, namely N-[4-[2-methyl-1-(1H-1,2,4-triazol-1-yl)propyl]-2-nitrophenyl]acetamide and 200 parts of a hydrochloric acid solution 2N was stirred for 12 hours at room temperature. The reaction mixture was poured into 500 parts of water and the whole was neutralized with a concentrated potassium carbonate solution. The product was extracted with dichloromethane (3×130 parts). The combined extracts were dried, filtered and evaporated to dry. The residue was crystallized from 2,2'-oxybispropane, yielding 18.5 parts (97.7%) of 4-[2-methyl-1-(1H-1,2,4-triazol-1-yl)propyl]-2-nitrobenzenamine; mp. 206° C. (interm. 18). In a similar manner there were also prepared:
