実験手順

1-(2-Amino-ethyl)-3-(4-methyl-benzo[b]thiophen-3-ylmethyl)-1,3-dihydro-benzimidazol-2-one (28 mg, 0.083 mmol) is added into DCM (1.0 mL) at room temperature and triethylamine (0.014 mL, 0.10 mmol) is added. Then Benzenesulfonyl isocyanate (0.014 mL, 0.10 mmol) is added into the above reaction mixture. After stirring for 2 hr, another 0.014 mL of Benzenesulfonyl isocyanate is added and the mixture is further stirred for 30 min. Then 1.0 mL of 1.0M HCl is added along with 5 mL of water. The mixture is extracted with EtOAc (3×20 mL) and the organic layers are combined, dried (Na2SO4) and concentrated to give crude product. Purification by preparative TLC affords 33 mg (76%) of the title compound. LCMS (ESMS): m/z 521.17 (M+H+).
