Procedure

(R)-2-Nitro-7-(4-piperazin-1-ylphenoxymethyl)-6,7-dihydro-5H-imidazo[2,1-b][1,3]oxazine (0.56 g) was added to an N-methylpyrrolidone solution (5 ml) of 1-(1-chloroethyl)-4-(4-trifluoromethylbenzyloxy)benzene (0.54 g). Subsequently, diisopropylethylamine (0.54 ml) was added thereto, and the mixture was stirred at room temperature for 12 hours. Thereafter, the mixture was heated to 60° C. and stirred for 7 hours. Water was added to the reaction mixture and the precipitated solid was collected by filtration. The solid thus obtained was purified by basic silica gel column chromatography (methylene chloride) and recrystallized from acetone-water to afford the title compound as a slightly yellow powder (0.15 g).
