Procedure
A solution of the compound (1b) (3.2 g, 14.5 mmol), EtOH (20 mL) and 1 N NaOH (20 mL, 20 mmol) was stirred at reflux under N2 for 1.5 hours. The reaction mixture was cooled and distributed between H2O (150 mL) and Et2O (150 mL). The organic layer was separated and washed with H2O (2×100 mL), dried and the clear faint yellow solution was evaporated. Distillation of the residue provided the compound (1c) as a clear colorless oil; bp 82°-87° C. (0.4 mm); NMR 3.3 (H, br s), 4.6 (2 H, s), 6.81 (H3, t, J=9 Hz), 7.15-7.37 (H4, m), 7.44 (H6, dd, J=3 and 6 Hz).
