Reaction Steps

1-Amino-3-[2-(4-methoxyphenyl)ethyl]-4-(4-methoxyphenyl)-2-imidazolidinone toluenesulfonic acid (0.3 g, 0.58 mmol) is stirred in dichloromethane (6 mL) and 3-pyridylsulfonylchloride HCl (135 mg, 0.63 mmol) is added followed by 4-methylmorpholine (0.2 mL). The mixture is heated in a microwave oven at 80° C. for 25 minutes. The mixture is evaporated and purified over silica (hexane/ethylacetate) to give the afford 0.12 g (41% yield) of the desired product as a white solid. 1H NMR (DMSO-d6) δ 10.3 (s, 1H), 9.0 (s, 1H), 8.9 (d, J=6 Hz, 1H), 8.2 (d, J=7.8 Hz, 1H), 7.65 (m, 1H), 7.2 (d, J=7.8 Hz, 2H), 7.05, (d, J=7.8 Hz, 2H), 6.95 (d, J=7.8 Hz, 2H), 6.8 (d, J=7.8 Hz, 2H), 4.5 (t, J=7 Hz, 1H), 3.8 (s, 3H), 3.75 (s, 3H), 3.3 (m, 1H), 3.2 (m, 1H), 2.75 (m, 2H), 2.4 (m, 2H). Anal. calcd. for C24H26N4O5S: C, 59.74; H, 5.43; N, 11.61; found C, 59.60; H, 5.47; N, 11.37. FAB-HRMS calcd. 483.1702; found 483.1720 (MH+).
