Procedure

To a solution of (R)-tert-butyl 2-(6-(3-(benzyloxy)phenylthio)naphthalen-2-yl)-1-hydroxypropan-2-ylcarbamate (20.0 mg, 0.0000388 mol) and 1H-tetrazole (30.4 mg, 0.000434 mol) in tetrahydrofuran (2 mL, 0.02 mol) was added di-tert-butyl N,N-diethylphosphoramidite (60.1 μL, 0.000216 mol) at room temperature. The resulting mixture was stirred at room temperature overnight, then hydrogen peroxide (180 μL, 0.0017 mol) was added and the mixture was stirred at room temperature for 1 h. The reaction was quenched with saturated. Na2S2O3, then extracted with EtOAc, and dried over Na2SO4. The residue was chromatographed with MeOH—CH2Cl2 (0-20%) to give (R)-tert-butyl 2-(6-(3-(benzyloxy)phenylthio)naphthalen-2-yl)-1-(di-tert-butoxyphosphoryloxy)propan-2-ylcarbamate as a gel (28 mg, 100%).
