2-Phenylbenzoxazole-7-carboxylic acid was prepared from 3-aminosalicyclic acid and benzoyl chloride using a procedure identical to that described in Step A of Example 1. This material was obtained in 86% yield as an off-white solid: 1H NMR (500 MHz, CD3OD) δ 8.30 (dd, J=7.2, 2.1 Hz, 2H), 7.98 (dd, J=12.9, 7.8 Hz, 2H), 7.60 (m, 3H), 7.48 (t, J=7.8 Hz, 1H); MS (APCI) m/z 240 [M+H]+
