실험 절차

To the product of Example 205 (0.020 g, 0.047 mmol) in pyridine (0.2 mL) was added 2,3-dichlorothiophene-5-sulfonyl chloride (0.015 g, 0.056 mmol). The reaction mixture was heated in a microwave reactor at 100° C. for 15 minutes. The reaction was diluted with ethyl acetate (40 mL), washed with 1 N hydrochloric acid, water, and brine. The organic layer was dried over magnesium sulfate, filtered and concentrated. The residue was chromatographed on silica gel eluting with 99:1 dichloromethane:methanol to give the title compound (14.8 mg, 50%). 1H NMR (300 MHz, DMSO-d6) δ 0.98 (d, J=6.25 Hz, 6 H) 1.56 (m, 2 H) 1.69 (m, 1 H) 4.47 (m, 2 H) 7.50 (m, 2 H) 7.56 (s, 1 H) 7.71 (d, J=8.82 Hz, 1 H) 7.76 (s, 1 H) 8.55 (dd, J=7.91, 2.02 Hz, 1 H) 8.88 (dd, J=4.60, 1.65 Hz, 1 H) 11.28 (s, 1 H) 14.19 (br s, 1 H).
