A solution of t-butylamine (6.00 g, 82 mmol) in MeCN (120 mL) was treated with 2-chloroethylisocyanate (9.00 g, 85 mmol), stirred at RT for 1 h, and the resulting solid was collected via filtration to afford 1-(tert-butyl)-3-(2-chloroethyl)urea (12.2 g, 83%) as a white solid. 1H NMR (400 MHz, DMSO-d6): δ 5.89 (t, J=5.9 Hz, 1 H), 5.82 (s, 1 H), 3.53 (t, J=6.2 Hz, 2 H), 3.24 (q, J=6.1 Hz, 2 H), 1.19 (s, 9 H); MS (ESI) m/z: 179.1 (M+H+).
