Pyridine → 2-Methyl-4-[(4-methylbenzenesulfonyl)oxy]butan-2-ol

Participants

Reaction Steps

3-Methyl-1,3-butanediol (1.5 mL, 14.06 mmol) is suspended in dry dichloromethane (5 mL) and pyridine (1.24 mL, 15.46 mmol) is added followed by 4-toluenesulfonyl chloride (2.68 g, 14.06 mmol). The mixture is stirred overnight then washed with 1M aqueous hydrochloric acid, dried and the solvent removed under vacuum. The residue is purified by flash chromatography (0-30% ethyl acetate in cyclohexane) to give the title compound. (Yield 970 mg).
