Reaction Steps

A mixture of ethyl 7-(methylsulfonyl)chromane-2-carboxylate (0.6 g, 2.1 mmol), LiBH4 (0.18 g, 8.5 mmol) and THF (8 ml) was stirred at 0° C. for 15 min and 2 h at room temperature. HCl (10%) and EtOAc was added, the organic phase was dried (Na2SO4), filtered and concentrated to give the title compound. Yield 0.66 g. MS m/z (rel. intensity, 70 eV) 507 (20), 485 (25), 265 (23), 244 (13), 243 (M+1, bp).
