Participants

Reaction Steps

A solution of the product from step 1 (3.2 g, 14 mmol) in CH2Cl2 (40 mL) was cooled to 0° C. and BBr3 (6.6 mL, 5.0 eq.) was added dropwise. The ice-bath was removed and the reaction was stirred at rt for 1 h, after which the reaction mixture was poured into 50 mL of ice cold saturated NH4Cl solution with stirring. The resulting solid was filtered, and washed with water (3×15 mL) then Et2O (2×15 mL) to give the product of step 2 (0.66 g, 22%): MS m/z 217 (M+H).
