The reaction mixture was poured into water (150 mL) and the whole was extracted with ethyl acetate/hexane/ether (2/1/1, 60 mL×3). The organic layer was washed with brine, dried over sodium sulfate, and concentrated in vacuo. The resulting solid (1.56 g, 7.64 mmol) was added HCl-MeOH reagent 10 (10 mL) at room temperature and stirred for 10 minutes. The mixture was concentrated in vacuo to give the subtitle compound (0.91 g, 49.4% yield).
