실험 절차

To a solution of the product of example 111 (4.32 g, 8.23 mmol) in MeOH (50 ml), 6N HCl (25 ml) was added drop-wise at room temperature. The mixture was stirred for 2 hours, after which saturated sodium bicarbonate was added to adjust the pH 9˜10, and then extracted with CH2Cl2. The extracts were combined, washed with brine, and then dried over sodium sulfate. The solvent was removed under pressure to give the titled product as yellow slide (3.0 g, 82% yield).
