실험 절차

A mixture of 5-fluoro-3-(4-piperidinyl)-1,3-benzoxazol-2(3H)-one hydrochloride D138 (0.2 g), 4-(ethyloxy)cyclohexanone (WO2007107566) (0.2 g), and Hunig's base (0.1 g) in N-methylpyrrolidone (5 mL) was stirred for 2 hours then treated with sodium triacetoxyborohydride (0.5 g) was added and stirring was continued for four days. The mixture was diluted with methanol, loaded onto a SCX column and the column was eluted with methanol followed by 2M ammonia in methanol. The methanolic ammonia fractions were evaporated and the residue was purified by high pH MDAP. Two peaks were collected and evaporated separately. The fast eluting isomer gave 3-{1-[trans-4-(ethyloxy)cyclohexyl]-4-piperidinyl}-5-fluoro-1,3-benzoxazol-2(3H)-one E52 as a white solid (7 mg).
