Procedure

4-nitrophthalic anhydride (0.25 g, 0.0013 mol) and m-aminobenzoic acid (0.18 g, 0.0013 mol) were refluxed as above overnight. The clear solution was purified as per 120 to yield 0.30 g (74%) 146 as a very pale dull yellow powder: mp=368-370° C.; Rf0.83 (A): Rf0.93 (C): Rf0.53 (D): IR (cm−1): 2700-3280 (OH), 3122 (C═CH), 2687 (C—H), 1781 (C═O), 1727 (bs, C═O), 1622 (C═C), 1588 (C═C), 1546 (N═O), 1461 (C═C), 1420 (C═C), 1386 (C—O), 1350 (N═O), 1113 (C—O), 727 (C═CH); MS m/z (rel intensity) 311 (68), 285 (46), 267 (46), 191 (100).
