Procedure
Intermediate 1 (5.3 g, 35 mmol) and hydrazine hydrate (1.8 mL, 38.3 mmol) in ethanol (20 mL) were refluxed overnight. Work-up (H2O/AcOEt) after cooling the mixture to ambient temperature gave the title compound as a brown solid. M.P.: 161-164° C. 1H-NMR (δ ppm, CDCl3, 400 MHz): 15.2 (bs, 1H), 5.65 (s, 1H), 2.16-2.09 (m, 2H), 1.18-1.14 (m, 4H), 0.98-0.94 (m, 4H). MS (m/z): 149.04 [M+H]+.
