실험 절차
To a stirred solution of Intermediate 212B (0.10 g, 0.47 mmol) in THF (5 mL) was added NaOH (0.038 g, 0.943 mmol) in water (1 mL) and the mixture was allowed to stir at 60° C. for 4 h. The reaction mixture was quenched with a 1.5 N aqueous solution of HCl and extracted with EtOAc (2×20 mL) The combined organic layers were dried over Na2SO4, filtered and the filtrate evaporated to afford Intermediate 212C as a light brown liquid (30 mg, 35% yield). 1H NMR (300 MHz, DMSO-d6) δ ppm 12.01-12.03 (bs, 1H), 3.34 (m, 2H), 1.04 (s, 6H).
