Procedure
2-Naphthoyl chloride (2.21 g, 11.6 mmol) was dissolved in a MeOH/NH3 solution (2 M, 20 mL) and was allowed to stir overnight. Volatiles were removed and the resulting white solid was triturated with EtOAc. The solid was filtered and washed with cold EtOAc to yield a white solid which was used without further purification (1.98 g, 100% yield). m.p. 191-192° C. 1H NMR (CDCl3) δ 8.39 (s, 1H, ArH), 7.90 (4H, ArH), 7.57 (m, 2H, ArH). 13C NMR (CDCl3) δ 169.3, 135.0, 132.6, 130.5, 129.0, 128.6, 128.1, 127.9, 127.8, 126.9, 123.7. IR (nujol) vmax cm−1: 3400, 3210, 1650, 1628, 1512, 1510.
