Reaction Steps

3-Ethyl-1-(2-hydroxy-ethyl)-1-(2-methoxy-5-nitro-benzyl)-urea (0.43 g, 0.0014 mol) in Ethanol (50 mL, 0.8 mol) was hydrogenated with 10% Pd/C (10:90, Palladium:carbon black, 0.027 g) catalyst overnight. The reaction was filtered and the filtrate evaporated to give 1-(5-Amino-2-methoxy-benzyl)-3-ethyl-1-(2-hydroxy-ethyl)-urea as a yellow oil (0.40 g, 75%). 0.020 g was chromatographed on Alumina with DCM/IPA (20-1) giving 1-(5-Amino-2-methoxy-benzyl)-3-ethyl-1-(2-hydroxy-ethyl)-urea as an oil (0.010 g). LCMS (m/e) 268 (M+1); 1H-NMR (DMSO, 400 MHz) δ 6.68 (d, 1H, J=8.59 Hz),6.44-6.39 (d, 1H, J=9.6 Hz), 6.32 (s, 1H), 6.26-6.23 (t, 1H, J=5.30 Hz), 4.79-4.76 (t, 1H, J=5.06 Hz), 4.59 (s, 2H), 4.15 (s, 2H), 3.65 (s, 3H), 3.47-3.43 (q, 2H, J=5.30 Hz), 3.20-3.17 (t, 2H, J=6.06 Hz), 3.08-3.00 (q, 2H, J=5.81 Hz), 1.07-0.98 (t, 3H, J=7.07 Hz).
