実験手順
A solution of cyclopropanamine (0.541 g, 9.48 mmol) in THF (10 mL) was treated with chloroethylisocyanate (1.0 g, 9.48 mmol), stirred at RT for 2 h, then concentrated to dryness and treated with MeCN. The resulting solid was collected via filtration and dried to afford 1-(2-chloroethyl)-3-cyclopropylurea (1.31 g, 85%). 1H NMR (400 MHz, DMSO-d6): δ 6.28 (s, 1 H), 6.12 (br s, 1 H), 3.55 (t, J=6.4 Hz, 2 H), 3.30 (m, 2 H), 2.36 (m, 1 H), 0.55 (m, 2 H), 0.31 (m, 2 H); MS (ESI) m/z: 162.9 (M+H+).
