Procedure

To a mixture consisting of 1-[3-(4-methoxymethoxy-phenyl)-4-phenyl-isoxazol-5-yl]cyclopropanecarbaldehyde (this example, Step A, 0.490 g) in dichloromethane (15 mL) is added 1-methyl-piperazine (0.173 mL) and sodium triacetoxyborohydride (0.420 g.) The mixture is stirred for two hours. Another portion of 1-methyl-piperazine (0.08 mL) and sodium triacetoxyborohydride (0.18 g) are added to the mixture and the mixture is stirred overnight. The mixture is treated with water and is extracted with dichloromethane. The organic layer is separated and is dried over anhydrous sodium sulfate. The mixture is filtered and the filtrate is concentrated under reduced pressure. The concentrate is purified by flash silica gel column chromatography to afford 1-{1-[3-(4-methoxymethoxy-phenyl)-4-phenyl-isoxazol-5-yl]-cyclopropylmethyl}-4-methyl-piperazine (0.500 g.)
