Reaction Steps

Referring to FIG. 39, chlorosulfonic acid (19.9 mL, 0.299 mol) was added dropwise to (prop-2-yn-1-yloxy)benzene (17.2 g, 0.130 mol) in dichloromethane (100 mL) at 0° C. The reaction was stirred at 0° C. for 1 hour and then poured into ice-water and extracted with dichloromethane. The extract was washed with water, dried (MgSO4), and evaporated. The residue was purified by Biotage flash column chromatography (30% EtOAc/Hep) to give product as an oil (17.9 g, 60%).
