Reaction Steps

To a solution of tert-butyl 2-(2,2-dimethyl-4H-benzo[d][1,3]dioxin-5-yl)acetate (2.6 g, 80% pure, 9.34 mmol, 1 eq.) in THF (20 mL) were added LiBH4 (7.0 mL, 14.01 mmol, 1.5 eq.) and MeOH (1.0 mL) at rt. The mixture was stirred at rt for 30 min, added MeOH (20 mL), concentrated to dryness, added MeOH (20 mL) and silica gel, and concentrated to dryness again. The mixture was loaded directly on silica gel for purification using a mixture of EtOAc and hexanes as eluent to give 2-(2,2-dimethyl-4H-benzo[d][1,3]dioxin-5-yl)ethanol (1.1 g, 71%) as a pale brown oil. 1H NMR (400 MHz, CDCl3) δ 7.28 (t, J=7.9 Hz, 1H), 6.92 (d, J=7.4 Hz, 1H), 6.86 (d, J=8.2 Hz, 1H), 5.02 (s, 2H), 3.99 (q, J=6.4 Hz, 2H), 2.86 (t, J=6.6 Hz, 2H), 1.68 (s, 6H), 1.57 (t, J=5.5 Hz, 1H).
