Procedure

Benzoyl isothiocyanate (3.40 mL, 25.3 mmol) was added to a solution of [(2R,4R,5S)-5-amino-2-[(benzyloxy)methyl]-5-(5-bromo-2-fluorophenyl)tetrahydro-2H-pyran-4-yl]methanol (C30) (10.84 g, 25.55 mmol) in dichloromethane (255 mL). The reaction mixture was stirred at room temperature for 48 hours and then concentrated under reduced pressure to afford the product as a light yellow solid (9.49 g), which was taken directly to the following step. LCMS m/z 587.0 [M−H+].
