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) 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.
