Procedure

A solution of (11S)-6-amino-11-isopropyl-10,11-dihydro-8H-[1,4]oxazino[4′,3′:1,2]imidazo[4,5-c]quinolin-3-ol (0.30 g, 1.0 mmol) dissolved in 5 mL of DMF was treated with cesium carbonate (1.0 g, 3.0 mmol) and 4-(bromoacetyl)morpholine (0.23 g, 1.1 mmol). After stirring for 18 hours at 65° C., the reaction mixture was concentrated under reduced pressure to give a solid. The solid was dissolved in CH2Cl2 (100 mL) and washed with H2O (100 mL). The organic layer was concentrated under reduced pressure to give a solid. Chromatography (SiO2, 0-15% CMA/CHCl3) gave a white solid which was crystallized from acetonitrile to give 0.18 g of the title compound as white crystals, mp 137-139° C.
