実験手順
To a mixture of ethyl 7-[(triisopropylsilyl)thio]chromane-2-carboxylate (5.6 g, 14.2 mmol) in EtOH (100 ml) was added concentrated HCl (4 ml) and the mixture was stirred at room temperature for 3 h. Evaporation to dryness gave the title compound. Yield: 3.4 g. MS m/z (rel. intensity, 70 eV) 238 (M+, 75), 165 (bp), 163 (56), 132 (50), 131 (43).
