Reaction Steps
Hydrogen chloride gas was bubbled though a solution of 3-isochromanone (1.2 g, 8.1 mmol) in methanol (30 mL) for 3 minutes. Reaction stirred at room temperature for 8 hours. Mixture was diluted with water (70 mL). Mixture was extracted with dichloromethane (2×40 mL). Combined organic layers were washed with brine (20 mL). Mixture was dried (magnesium sulfate), filtered and concentrated in vacuo. Title compound was obtained as clear colorless oil in 90% yield. 1H NMR (300 MHz, CDCl3): δ=7.40-7.26 (m, 4H), 4.67 (s, 2H), 3.80 (s, 2H), 3.69 (s, 3H).
