Procedure

Acetaldehyde (2.2 ml) was added to an acetic acid solution (11 ml) of N-{1-[4-((R)-2-nitro-6,7-dihydro-5H-imidazo[2,1-b][1,3]oxazin-7-ylmethoxy)phenyl]piperidin-4-yl}-N-(4-trifluoromethylphenyl)amine (2.2 g). Subsequently, sodium triacetoxyborohydride (2.52 g) was added thereto, and the mixture was stirred at room temperature for 3 hours. The reaction mixture was poured into ice water, and neutralized with a 5 N sodium hydroxide aqueous solution and a saturated sodium hydrogen carbonate aqueous solution. The resulting precipitate was collected by filtration and dried. The solid thus obtained was purified by silica gel column chromatography (methylene chloride:ethyl acetate=50:50) and recrystallized from acetone-ethyl acetate to afford the title compound as a yellow powder (1.96 g).
