Reaction Steps

To a solution of (R,E)-2-methyl-N-(1-(tetrahydro-2H-pyran-4-yl)ethylidene)propane-2-sulfinamide (1.25 g, 5.4 mmol) in tetrahydrofuran (6 mL) was added methanol (692 mg, 21.6 mmol) and NaBH4 (821 mg, 21.6 mmol) at −65° C. under N2. The reaction was stirred at −65-0° C. for 2 h. Then the reaction was quenched by water and extracted with ethyl acetate. The organic layer was washed with saturated aqueous NaHCO3 and concentrated in vacuo to give crude (R)-2-methyl-N-(1-(tetrahydro-2H-pyran-4-yl)ethyl)Propane-2-sulfinamide (1.2 g, 52.1%) as a yellow oil.
