実験手順
A solution in ethanol (50 mL) of 2-(2-oxopropyl)-4H-3,1-benzoxazin-4-one (11.2 g, 55.1 mmol) and 3-hydrazinomethylpyridine (7.44 g, 60.4 mmol) which was prepared from 3-chloromethylpyridine following the method described in Reference Example 2-2, was heated under reflux for 1 hour. The solution was cooled to room temperature, and the resulting crude crystals were collected by filtration. The crystals were washed with ethanol and air dried to give the title compound (11.3 g, 67% yield). mp: 180-183° C. (recrystallized from ethanol).
