実験手順
Compound (60) (2.0 g, 5.6 mmol) was refluxed with conc. HCl (30 ml) for 3 hr. After cooling to room temperature, the white precipitate was collected by filtration, washed with cold water, and dried in high vacuo to afford 1.6 g (87%) of the title compound as a white solid. m.p. 252-253° C.; 1H NMR (200 MHz, CDCl3/CD3OD) δ 1.11 (6H, d, J=6.9 Hz), 2.33 (1H, m), 7.61-7.73 (3H, m); HRMS (EI) Calcd. 326.0225, Found 326.0240.
