Procedure

A mixture of 5-(tert-butyloxycarbonyl)-3-(5-cyclopropyl-1,2,4-oxadiazol-3-yl)-6-fluoro-4,5-dihydroimidazo[1,5-a]quinoxaline (I, EXAMPLE 51, 3.39 g) and 50 ml of methanol saturated with HCI(g) is stirred at 20°-25° overnight. The solvent is then removed under reduced pressure and the residue is partitioned between dichloromethane and aqueous sodium bicarbonate. The organic phase is separated and dried over sodium sulfate and taken to dryness to give the title compound, NMR (CDCl3) 1.23, 1.35, 2.26, 4.32, 4.86, 6.80, 6.95, 7.22 and 8.06 δ.
