実験手順
Compound (27) (34.6 g, 91 mmol) was refluxed with conc. HCl (200 ml) for 3 hr. After cooling to room temperature, the white precipitate was collected by filtration, washed with cold water and hexane, and dried in high vacuo to afford 30 g (94%) of a white solid; m.p. 266-267° C.; 1H NMR (200 MHz, DMSO-d6) δ 1.05 (6H, d, J=6.8 Hz), 2.26 (1H, m), 2.40 (3H, s), 7.82 (2H, s), 7.93 (1H, s), 11.02 (1H, s), 11.17 (1H, s).
