실험 절차
A mixture of (R)-1-methoxypropan-2-amine hydrochloride (500 mg, 3.98 mmol) and pyridine (315 mg, 3.98 mmol) in THF (15 mL) was treated drop-wise with 2-chloroethylisocyanate (420 mg, 3.98 mmol) and stirred at RT overnight. The mixture was concentrated to dryness, partitioned between EtOAc and brine and the organic layer dried over Na2SO4 and concentrated to dryness to afford (S)-1-(2-chloroethyl)-3-(1-methoxypropan-2-yl)urea (393 mg, 50%). 1H NMR (400 MHz, DMSO-d6): δ 6.08 (s, 1 H), 5.93 (d, J=8.1 Hz, 1 H), 3.71 (m, 1 H), 3.56-3.51 (m, 3 H), 3.30-3.23 (m, 3 H), 3.22 (s, 3 H), 0.98 (d, J=6.7 Hz, 3H).
