To a suspension of 2.16 g (0.054 mole) of sodium hydride in 20 ml of dimethylformamide was added dropwise a solution of 2.92 g (0.043 mole) of pyrazole in 10 ml of dimethylformamide. There was a slight exotherm at this point with some evolution of hydrogen gas. The resulting solution was then added dropwise to a solution of 10.0 g (0.039 mole) of 2-(2-chloroethyl)-2,3-dihydro-4-methylpyrido[3,2-f]-1,4-oxazepine-5(4H)-thione in 30 ml of dimethylformamide. The reaction flask was sealed and stirred overnight at room temperature.
