Participants

Reaction Conditions

Reaction Steps

To a solution of (3,5-dichlorophenyl)methanol (10.0 g, 56.5 mmol) in methylene chloride (100 mL) at 0° C. was added 2,6-lutidine (16.4 mL, 141 mmol) followed by triisopropylsilyl triflate (19.7 mL, 73.4 mmol), and was stirred at 0° C. for 2 hours. The reaction was diluted with water and the organic layer was separated, washed with brine, dried over Na2SO4, filtered and concentrated. The residue was purified by chromatography on silica gel, eluting with hexane to provide the desired product (14.8 g, 79%). LC/MS: 333 (M+H)+, 1H NMR (CDCl3) δ 7.23 (s, 3H), 4.78 (s, 2H), 1.18 (m, 3H), 1.03 (s, 18H).
