Procedure
A stirred mixture of 6-fluoro-3-(4-piperidinyl)-1H-indazole (3.5 g, 16 mmol), K2CO3 (2.2 g), 1-[4-(3-chloropropoxy)-3-methoxyphenyl]ethanone (3.8 g, 16 mmol) a acetonitrile (90 ml) was refluxed for 16 hours. The reaction was poured into water and the resulting white solid, which precipitated from solution, was collected to afford 5.5 g of the desired product. The compound was recrystallized from dimethylformamide (twice) to afford 3.0 g (44%) of 1-[4-[3-[4-(6-fluoro-1H-indazol-3-yl)-1-piperidinyl]propoxy]-methoxyphenyl]ethanone as a white solid, m.p.=202°-204° C.
