Tributyltin Chloride → 1-[6-(Tributylstannyl)pyridin-2-yl]cyclobutanol

Participants

Reaction Steps

Tetrahydrofuran (10 mL) solution of 293.1 mg of 1-(6-bromo-2-pyridinyl)cyclobutanol obtained in Example 69-1 was cooled to −78° C. in an acetone/dry ice bath in a nitrogen atmosphere, and 1.8 mL of 1.58 M n-butyllithium/hexane solution was gradually added thereto, and stirred for 30 minutes. Subsequently, tetrahydrofuran (2.0 mL) solution of 0.36 mL of tri-n-butyltin chloride was added thereto at −78° C., and the reaction solution was stirred for 30 minutes. This was processed with aqueous saturated ammonium chloride solution, extracted with ethyl acetate, and the organic layer was washed with saturated saline water, and purified through silica gel column chromatography (hexane/ethyl acetate) to obtain 48.7 mg of the entitled compound as a pale yellow oily substance.
