Reaction Steps

To a solution of 5-{[(methyloxy)methyl]oxy}-1H-spiro[2-benzopyran-4,1′-cyclopropane] (Intermediate 135, 380 mg) in methanol (10 mL) HCl 10% in water (1.048 mL, 3.45 mmol) was added and the reaction mixture was stirred overnight at 50° C. The combined solvents were evaporated and the residue was purified by flash chromatography (Biotage system) on silica gel using a 25 g SNAP column and cyclohexane/ethyl acetate as eluents from 100:0 to 8:2. This afforded the title compound as a white solid (260 mg).
