실험 절차

To an ice-cooled suspension of 1-amino-2-methyl-2-propanethiol hydrochloride (1.08 g, 7.62 mmol) in methylene chloride (20 mL) was added triethylamine (1.2 mL, 8.61 mmol) followed by dibenzo[c,e]oxepin-5,7-dione (1.68 g, 7.42 mmol). After stirring at room temperature for 1 h, cold 2 N HCl (50 mL) was added. After separation, the aqueous layer was extracted with dichloromethane (2×15 mL). The combined organic layers were washed with brine and dried under sodium sulfate. The solvent was removed and the resulting residue was triturated with hexane to give the title compound as white solid (2.44 g, 98.9%). mp 150-153° C.; 1H NMR (CDCl3, 300 MHz): δ1.03 (s, 3H), 1.12 (s, 3H), 1.36 (s, 1H), 3.15 (dd, J=13.7 and 5.7 Hz, 1H), 3.38 (dd, J=13.7 and 6.9 Hz, 1H), 6.92 (t, J=6.1 Hz, 1H), 7.09-7.17 (m 2H), 7.38-7.48 (m, 4H), 7.57-7.61 (m, 1H), 7.80-7.83 (m, 1H); 13C NMR (CDCl3, 75 MHz,): δ29.36, 29.75, 44.66, 53.01, 127.28, 127.96, 128.04, 129.38, 129.93, 130.06, 130.20, 131.19, 132.02, 134.69, 138.90, 140.11, 170.99, 171.24; LCMS (m/e): 330 (M+1).
