Procedure

4-nitrophthalic anhydride (0.25 g, 0.0013 mol) and β-alanine (0.115 g, 0.0013 mol) were refluxed as above overnight. The clear solution was purified as per 120 to yield 0.31 g (90%) 141 as a very pale yellow powder: mp=206–208° C.; Rf 0.84 (A): Rf 0.81 (B): Rf 0.55 (D): IR (cm−1): 2800–3125 (OH), 3109 (C═CH), 2646 (C—H), 1780 (C═O), 1718 (bs, C═O), 1621 (C═C), 1536 (N═O), 1441 (C═C), 1395 (C—O), 1346 (N═O), 1228 (C—O), 724 (C═CH); MS m/z (rel intensity) 263 (100), 191 (36).
