A solution of ethyl 2-(1-methyl-4-(3-(4-octylphenyl)ureido)piperidin-4-yl)acetate (73 mg, 0.169 mmol) in CH2Cl2 (5 mL) was treated with MeI (0.11 mL, 1.69 mmol) and the reaction stirred overnight at room temperature. The solvent was removed in vacuo to yield crude title compound (95 mg, 98%) which was used without further purification. 1H NMR (400 MHz, CDCl3) δ 8.35 (bs, 1H), 7.42 (d, 2H, J=8.4 Hz), 7.05 (d, 2H, J=8.4 Hz), 6.49 (bs, 1H), 4.39-4.32 (m, 2H), 4.14 (q, 2H, J=7.2 Hz), 3.41-3.34 (m, 5H), 3.21 (s, 2H), 3.20 (s, 3H), 2.64-2.41 (m, 6H), 1.29-1.20 (m, 13H), 0.89 (t, 3H, 6.4 Hz); MS ESI 446.4 [M]+, calcd for [C26H44N3O3]+ 446.65.
