실험 절차

N-[(4aR,6S,8aS)-8a-(2,4-Difluoro-5-{[(2,2,2-trifluoroethyl)amino]methyl}phenyl)-6-methyl-4,4a,5,6,8,8a-hexahydropyrano[3,4-d][1,3]thiazin-2-yl]benzamide (C28) was converted to the product according to the method described for the synthesis of (4aR,6R,8aS)-8a-(2,4-difluoro-5-{[(2,2,2-trifluoroethyl)amino]methyl}phenyl)-6-(fluoromethyl)-4,4a,5,6,8,8a-hexahydropyrano[3,4-d][1,3]thiazin-2-amine (8) in Example 8. Purification via silica gel chromatography (Gradient: 0% to 20% methanol in dichloromethane) afforded the product as a white solid. Yield: 12 mg, 25%. LCMS m/z 410 [M+H+]. 1H NMR (400 MHz, CD3OD) δ 7.39 (t, J=8.7 Hz, 1H), 7.00 (dd, J=12.3, 9.6 Hz, 1H), 4.07 (dd, J=11.3, 2.0 Hz, 1H), 3.70-3.79 (m, 2H), 3.18 (q, J=9.3 Hz, 2H), 2.91-3.02 (m, 2H), 2.73 (dd, J=12.5, 2.7 Hz, 1H), 1.58-1.73 (m, 2H), 1.24 (d, J=8.0 Hz, 3H).
