Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To the mixture of 2-(bromomethyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (2.0 g, 8.3 mmol) synthesized in Production Example 2 and acetone (17 ml), sodium iodide (1.9 g, 13 mmol) was added at room temperature, and the obtained reaction mixture was stirred at room temperature for 2 hours. Impurities were removed by filtration, and the solvents were evaporated under reduced pressure from the filtrate. Hexane was added to the obtained residue, and insoluble matter was removed by filtration. The solvents were evaporated under reduced pressure from the filtrate, thereby obtaining the entitled compound (2.2 g, 97%). was added at room temperature the obtained reaction mixture Impurities were removed by filtration the solvents were evaporated under reduced pressure from the filtrate Hexane was added to the obtained residue, and insoluble matter was removed by filtration The solvents were evaporated under reduced pressure from the filtrate
