Procedure

To a solution of methyl-1-H-indazole-3-ylacetate (1.9 g) in dimethylformamide (4 ml) was added sodium hydride (0.58 g; 50% by weight dispersed in oil) and the mixture stirred for 15 minutes at room temperature. Chloroacetonitrile (1.9 g) dissolved in dimethylformamide (2 ml) was then added and the reaction mixture stirred for 6 hours. The mixture was then poured onto ice-water (20 ml), the pH was adjusted to about 3 by the addition of sufficient dilute HCl, and the resulting precipitate was collected and air-dried (yield 1.87 g) m.p. 128°-134° C.
