Reaction Steps

To a solution of methyl 3,3-dimethyl-2,3-dihydro-1-benzofuran-6-carboxylate (44 mg, 0.21 mmol) prepared in the method of US2009/105209 in tetrahydrofuran (1.5 mL) were added lithium borohydride (23 mg, 1.07 mmol) and methanol (43 μL, 1.07 mmol) at 0° C., and the mixture was stirred at room temperature for 1 hour. To the reaction solution was added water, and the mixture was extracted with ethyl acetate twice. The organic layer was combined, washed with water and saturated brine, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure to give the title compound (38 mg, 100%) as a colorless and clear oil.
