Procedure
A mixture of 6-fluoro-3-(4-piperidinyl)-1,2-benzisoxazole (4.3 g, 0.0195 mol), 4-(3-chloropropoxy)-3-hydroxy-α-methylbenzenemethanol (4.5 g, 0.0195 mol), KI (200 mg), NaHCO3 (1.8 g, 0.0215 mol) and CH3CN (125 ml) was stirred at reflux under nitrogen for 24 hours. The cooled reaction was filtered and the filter cake was washed with CH3CN. The filtrate was concentrated to afford an oily residue, which was partitioned between water and ethyl acetate. The ethyl acetate extract was washed with water, dried with MgSO4, and concentrated to yield 8.6 g of a dark oil. The oil was purified by preparative HPLC (Waters Associates prep LC/system 500) to yield 5.0 g. The compound was recrystallized twice from ethanol to provide 3.9 g (49%) of 4-[3-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]propoxy]-3-hydroxy-α-methylbenzene methanol as a light beige solid, m.p.=142°-144° C.
