실험 절차

To a solution of 2-{[1-(cyclopropylmethyl)-2-(2,2-dimethylpropyl)-1H-benzimidazol-5-yl]sulfonyl}-2-methylpropan-1-amine (Step K, 132 mg, 0.350 mmol) and triethylamine (98 μL, 0.700 mmol) in dichloromethane (4 mL) was added acetyl chloride (0.03 mL, 0.420 mmol) at room temperature. After stirring for 15 min, the mixture was concentrated under reduced pressure. The residue was purified by HPLC (ODS, gradient elution with Acetonitrile/0.01% aq. NH3=4:96 to 96:4, by volume; flow rate 40 mL/min) to afford the title compound (113 mg, 77%) as an amorphous.
