실험 절차

To a solution of the (2R)-2-phenylpropylamine (1.2g, 8.87mmol) in hexane (16.0 mL) was added triethylamine (2.47 mL, 17.74 mmol) and dimethylaminopyridine (0.30 g, 2.47 mmol). Cooled reaction to 5° C., then added a solution of isopropylsulfonyl chloride (0.97 mL, 8.69 mmol) dissolved in methylene chloride (6.0 mL) over a period of 15.0 minutes. Stirred for 45.0 minutes, then stirred at room temperature for 120.0 minutes. Quenched reaction with IN HCl (20.0 mL) and extracted organic with methylene chloride (25.0 mL). Dried organic layer with anhydrous magnesium sulfate, filtered and concentrated filtrate to provide the final title compound, ((2R)-2-phenylpropyl)[(methylethyl)sulfonyl]amine, (1.93 g, 90.1%) an oil; 1H nmr (CDCl3, 300 MHz) δ 1.25 (d, 3H, J=6.9Hz), 1.29(d, 3H, J=6.9Hz), 1.30 (d, 3H, J=7.2 Hz), 2.98 (m, 1H), 3.05 (m, 1H), 3.22 (m, 1H), 3.36 (m, 1H), 3.89 (b, 1H), 7.23 (m, 2H), 7.34 (m, 2H).
