Participants

Reaction Steps

To a solution of 3-{4-[(6-fluoropyridin-2-yl)oxy]-3-methoxyphenyl}prop-2-yn-ol (0.37 mmol; 102 mg) in dry dichloromethane (2 mL), under argon, cooled to −40° C., was added triethylamine (0.41 mmol; 56 μL) then methanesulfonyl chloride (0.39 mmol; 30 μL). The reaction mixture was allowed to stir for 6 hr, with gradual warming to room temperature. The reaction was hydrolysed with saturated NH4Cl, extracted with ethyl acetate. Combined organic phases were dried over Na2SO4, concentrated in vacuo. The title compound (185 mg; 47%) was obtained as a light oil, after purification on preparative TLC (cyclohexane/ethyl acetate: 7/3).
