Procedure

Benzoyl isothiocyanate (17.8 mL, 132 mmol) was added to a solution of [(2R,4R,5S)-5-amino-2-[(benzyloxy)methyl]-5-(2,4-difluorophenyl)tetrahydro-2H-pyran-4-yl]methanol (C6) (48.7 g, 134 mmol) in dichloromethane (1.34 L), and the reaction mixture was allowed to stir at room temperature for 18 hours. Removal of solvent in vacuo afforded the product as a white solid, which was used without additional purification. Yield: 72.2 g, assumed quantitative. LCMS m/z 527.2 [M+H+]. 1H NMR (400 MHz, CD3OD), characteristic peaks: δ 7.89-7.93 (m, 2H), 7.62-7.67 (m, 1H), 7.50-7.56 (m, 2H), 7.42-7.54 (br m, 1H), 7.31-7.36 (m, 2H), 7.17-7.28 (m, 3H), 6.86-6.98 (m, 2H), 4.57 (AB quartet, JAB=11.9 Hz, ΔνAB=11.8 Hz, 2H), 3.84-3.91 (m, 1H), 3.64 (br dd, half of ABX pattern, J=10.6, 6.0 Hz, 1H), 3.58 (dd, half of ABX pattern, J=10.6, 3.8 Hz, 1H), 3.44-3.54 (br m, 1H), 2.32-2.59 (br m, 1H), 1.82-2.06 (m, 2H).
