Reaction Steps

A suspension of 2.4 g. of sodium hydride and 50 ml. of benzene is added to a mixture of 23 g. of 6-fluoro-2-naphthyl-α-methylacetic acid and 450 ml. of benzene. The resulting mixture is stirred for four hours. The mixture is cooled to 0°C and 19 g. of oxalyl chloride are added; after the addition, the mixture is allowed to stand for four hours. The resulting mixture is then saturated with ammonia and allowed to stand for eight hours. This mixture is then evaporated under reduced pressure. The residue is taken up in methylene chloride, washed with water to neutrality, dried, filtered, and evaporated to give 6-fluoro-2-naphthyl-α-methylacetamide.
