Procedure

To a solution of 0.24 g (0.95 mmol) of the above (3-methanesulfonyl-phenylethynyl)-trimethyl-silane in methanol (2 mL) was added K2CO3 aq. solution (1 M, 1 mL), the mixture was stirred at room temperature for 1 h. After usual workup, the residue was purified by column chromatography eluted with hexanes/ethyl acetate (v/v=5:1 then 3:1) to give 140 mg (82%) 1-ethynyl-3-methanesulfonyl-benzene.

Workup

  1. customAfter usual workup, the residue was purified by column chromatography
