Procedure

A mixture of 3-(5-cyclopropyl-1,2,4-oxadiazol-3-yl)-4,5-dihydro-4-oxo-5-(4-phthalimidobenzyl)-imidazo[1,5-a]quinoxaline (0.46 g, 0.87 mmol) and hydrazine (2 ml) in ethanol (25 ml) was stirred at room temperature for 1.5 h. The precipitate was collected by filtration, washed with ethanol and dried to give the title compound, m.p. 246°-248° C.
