Reaction Steps

A mixture of methyl [1-[4-methoxy-3-methylphenyl]hydrazino]acetate (Intermediate 97, 380 mg, 0.0017 mol), sodium cyanate (380 mg, 0.0058 mol) and trifluoroacetic acid (0.4 ml, 0.0052 mol) in dry toluene (10 ml) was stirred under nitrogen and at room temperature for 31/2 hours. It was poured into 8% sodium bicarbonate solution (20 ml) and extracted with ethyl acetate (2×20 ml). The organic extract was dried (MgSO4) and evaporated to give a yellow solid which was triturated with ether and filtered to give the title compound as a yellow solid (237 mg, 52%) m.p. 174°-176° C.
