A solution of 5-bromo-3,4-dihydro-1H-isochromene-1-carboxylic acid (0.500 g, 1.94 mmol) in 1 mL of THF was added BH3.THF (3.88 mL, 3.88 mmol) drop wise at 0° C. The mixture was stirred at 0° C. for 2 h. The reaction was quenched with water and aqueous sodium hydroxide (1 N, 2 mL). The contents were stirred for 3 h, and then extracted with EtOAc. The organic layer was dried and concentrated to give (5-bromo-3,4-dihydro-1H-isochromen-1-yl)methanol
