Reaction Steps

A solution of methyl N′-(3-fluorophenyl)-N-[4-[1-(1H-imidazol-1-yl)-2-methylpropyl]-phenyl]carbamimidothioate (0.0094 mol) in NH3/CH3OH (60 ml) was stirred and heated in autoclave at 40° C. for 3 days. The solvent was evaporated and the residue was purified by column chromatography over silica gel (eluent: CH2Cl2/CH3OH/NH4OH 94/6/0.2 to 90.10/0.5). The pure fractions were collected and evaporated. The residue was crystallized from 2-propanone and (C2H5)2O and filtered off, yielding 0.89 g (46%) N′-(3-fluorophenyl)-N-[4-[1-(1H-imidazol-1-yl)-2-methylpropyl]phenyl]guanidine (compound 744).
