Participants

Reaction Steps

To a solution of 180 mg of 1-phenyl-prop-2-ynylamine (Formula 28) in 5 mL of CH2Cl2 were added 0.1 mL of 2-chloroethyl isocyanate and 0.2 mL of triethylamine. After the mixture was stirred at room temperature for 2 hours, the solvent was removed. Column chromatography (50% ethyl acetate/hexane) gave 153 mg of 1-(2-chloro-ethyl)-3-(1-phenyl-prop-2-ynyl)-urea (Formula 29) as a white solid. 1H NMR (300 MHz, CDCl3) δ 2.46 (m, 1H), 3.45-3.49 (m, 2H), 3.52-3.54 (m, 2H), 5.40-5.41 (m, 1H), 5.55-5.57 (m, 1H), 5.74-5.76 (m, 1H), 7.27-7.35 (m, 3H), 7.48-7.50 (m, 2H).
