実験手順

To a solution of Step 2 intermediate (0.40 g, 1.573 mmol) in MeOH (80 mL) was added 10% Pd—C (0.2 g) and the mixture was stirred under a hydrogen atmosphere at room temperature for 2 h. The mixture was filtered through a celite bed and was thoroughly washed with MeOH (50 mL). The filtrate was collected and evaporated and the residue thus obtained was purified by column chromatography to afford 0.120 g of the desired compound as an off-white solid; 1H NMR (δ ppm, 300 MHz, DMSO-d6) 3.23 (s, 3H), 3.38 (s, 3H), 6.17 (s, 1H), 7.25 (s, 1H), 12.09 (s, 1H); APCI-MS (m/z) 180.28 (M+H)+.
