Reaction Steps

To a solution of 4-{[(methyloxy)methyl]oxy}spiro[1-benzofuran-3,1′-cyclopropane] (Reference Intermediate 213, 118 mg) in methanol (5 ml), HCl 2N in water (0.286 mL, 0.572 mmol) was added and the reaction mixture was stirred overnight at 50° C. Combined solvents were removed under reduced pressure and the residue was re-dissolved in toluen (10 ml) and the solvent was removed. The residue was purified by flash chromatography (Biotage system) on silica gel using a 10 g SNAP column and cyclohexane to cyclohexane/ethyl acetate 7:3 as eluents affording the title compound as a white solid (70 mg).
