An ethereal solution of diazomethane is prepared from n-methyl-n-nitro-n-nitroso guanidine (15.72 g) for an estimated yield of 64 mmol. To the ethereal solution (400 ml) at 0° is added triethylamine (9.0 ml, 64 mmol), then dropwise benzoyl chloride (7.4 ml, 64 mmol). The reaction is warmed to 22° and stirred for 20 hrs, then filtered through celite and concentrated. The residue is recrystallized from ether/pentane to give the title compound.
