Procedure:
t-Butyl 6-acetylpyridazin-3-yl((1-(3-fluoropyridin-2-yl)cyclobutyl)methyl)carbamate (2.5 g, 6.2 mmol) in THF (150 mL) was treated with NaOEt (3.44 g, 10.6 mmol, 21% in EtOH). The resulting mixture was then treated with diethyl oxalate (1.7 mL, 12.5 mmol), heated to 45° C., and stirred for 4 h. The reaction mixture was added to 1N HCl, extracted with EtOAc, and washed with satd. aq. NaHCO3 and brine. The organic layer was dried over sodium sulfate, filtered, and concentrated.

Procedure:
A stirred mixture of 6-fluoro-3-(4-piperidinyl)-1,2-benzisoxazole (2.45 g; 11.1 mmol), K2CO3 (2.0 g), and 3-(2-methoxyphenoxy)propyl chloride (3.5 g, 17.4 mmol) in acetonitrile (40 ml) was heated at 90° C. for 4 hours. At the end of the reaction, the solvent was removed, and the solids were dissolved into dichloromethane (100 ml). The solution was washed with water and brine, then dried over MgSO4. The crude material from the solution was combined with 1.2 g of crude material prepared in the same fashion (using 0.5 g of starting material). The combined material was purified by flash chromatography on a silica gel column (49 g, eluted with 0.5% diethylamine:1% methanol:98.5% dichloromethane, 1 L). The fractions containing the pure product were pooled and concentrated down to a light oil (3.68 g). This oil was treated with fumaric acid (1.14 g, 9.8 retool) in ethanol (13 ml). The 6-fluoro-3-[1-[3-(2-methoxyphenoxy)-propyl]-4-piperidinyl]-1,2-benzisoxazole fumarate crystals obtained weighed 4.01 g (60%), m.p.=169°-170° C.
