Reaction Steps

A solution of (R,E)-N-((5-(cyclopropylmethoxy)pyridin-2-yl)methylene)-2-methylpropane-2-sulfinamide (6.2 g, 22 mmol) was dissolved into dichloromethane (110 ml). Methyl magnesium bromide (44 ml, 44 mmol, 1.0M in THF) was added to the mixture at −78° C. dropwise. The mixture was stirred for 1 h at −78° C. The mixture was poured into saturated ammonium chloride aqueous solution, and the aqueous phase was extracted with ethyl acetate (twice). The combined organic layers were dried over magnesium sulfate and concentrated in vacuo. The residue was purified by column chromatography on silica gel eluting with hexane/ethyl acetate (1:1 (v/v)) to give 3.2 g (49% yield) of the title compound as a white solid:
