Procedure

A mixture of 0.7 gm. of the above crude 4-(benzoxazol-2-yl)-3-fluorophenylacetonitrile and 30 cc. of concentrated hydrochloric acid is heated on the steam bath for 1 hour. The reaction mixture is then filtered through a sintered glass filter into ice water and the resulting precipitate collected to give 0.65 gm. of crude product. The crude acid is stirred with 50-60 cc. of saturated sodium bicarbonate solution, a small amount of charcoal is added, and the mixture is then filtered. The filtrate is acidified with concentrated hydrochloric acid and the resulting precipitate collected and dried to give 4-(benzoxazol-2-yl)-3-fluorophenylacetic acid, m.p. 207°-211° C. dec.
