실험 절차

To a stirred solution of benzo[b]thiophen-4-amine (1 g, 6.70 mmol) and pyridine (1.355 mL, 16.75 mmol) in CH2Cl2 (15 mL) was added dropwise methanesulfonyl chloride (0.574 mL, 7.37 mmol) at 0° C. under nitrogen atmosphere. The reaction mixture was then allowed to warm to room temperature while stirring overnight. The reaction mixture was washed with saturated sodium bicarbonate solution, water, brine and dried over sodium sulfate. Evaporation of the solvent furnished a crude residue, which was subjected to BIOTAGE® (100% methylene chloride) to give the title compound as a white solid (1.2 g, 79%). LC/MS: Example 105A @ 2.88 min (RT) (Condition H). MS (ES): m/z=226.0, [M+H]+. 1H NMR (400 MHz, MeOD) δ ppm 7.77 (1 hr, d, J=7.81 Hz), 7.59 (2 hr, d, J=1.26 Hz), 7.25-7.42 (2 hr, m), 2.94 (3 hr, s).
