Methylhydrazine (0.212 ml, 4.0 mmol) was dissolved in dichloromethane (10 ml) and was treated dropwise with benzoylchloride (0.232 ml, 2.0 mmol) in dichloromethane (5 ml). After stirring for 0.5h the solution was evaporated to dryness. The residue was partitioned between water and ethyl acetate. The organic phase was dried and evaporated under reduced pressure to give the title compound (0.20 g, 65%); δH (CDCl3) 3.13 (3H, s), 4.5 (2H, brs), and 7.30 (5H, s).
