実験手順
1,2-Diaminopropane (1.00 g, 13.5 mmol, 1.15 mL, 1.1 eq.) was placed in CH2Cl2 (30 mL) and cooled to 0° C. Mesyl chloride (1.40 g, 12.3 mmol, 0.95 mL, 1.0 eq.) was added over a period of five minutes followed by triethylamine (3.72 g, 36.9 mmol, 5.17 mL, 3.0 eq.). The reaction was stirred for 30 minutes and then concentrated under reduced pressure. Purification by basic alumina chromatography using a gradient of 0-15% MeOH/CH2Cl2 as the eluting solvent to obtain N-(2-amino-propyl)-methanesulfonamide as a clear, colorless oil (504 mg, 27%). 1H-NMR (CDCl3, 400 MHz) δ 3.17-3.03 (m, 2H), 2.98 (s, 3H), 2.88-2.80 (m, 1H), 1.12 (d, 3H, J=6.3 Hz).
