実験手順

To the solution (3aS,7aS)-1-[1-(4-methyl-4-piperidyl)-4-piperidyl]-3a,4,5,6,7,7a-hexahydro-3H-benzoimidazol-2-one (99 mg, 0.25 mmol) in dry DMF (3 mL) was added cyclopropanecarboxylic acid (26 mg, 0.3 mmol) followed by HATU (114 mg, 0.3 mmol) and diisopropylethylamine (0.10 mL, 0.5 mmol) and stirred at room temperature for 1 h. The solvent was removed in vacuo, dichloromethane added (15 mL), washed with saturated NaHCO3 (10 mL) and brine (10 mL), dried over Na2SO4 and concentrated in vacuo. The residue was purified with preparative LC/MS (high pH) to yield the title compound (59 mg, 61%) as white powder. 1H NMR (400 MHz, METHANOL-D4) δ ppm 0.71-0.89 (m, 4H), 1.00 (s, 3H), 1.28-1.46 (m, 5H), 1.50-1.68 (m, 2H), 1.68-1.89 (m, 8H), 1.89-2.00 (m, 2H), 2.11-2.31 (m, 2H), 2.86-3.02 (m, 2H), 3.02-3.14 (m, 2H), 3.47-3.70 (m, 4H), 3.75-3.91 (m, 1H). MS (M+1): 389.2.
