Participants

Reaction Steps

To a 250 mL 3-neck round bottom flask fitted with a magnetic stirrer, condenser, thermometer, ice water bath, dropping funnel, was added 10.0 g (64.0 mmol) of 4-t-butylcyclohexanol, 5.6 g (70.3 mmol) of pyridine and 100 mL of chloroform. The reaction mixture was cooled to less than 10° C. and 6.8 g (64.0 mmol) of vinyl chloroformate was added so that the temperature remained below 15° C. The reaction mixture was stirred at room temperature for 20 hours, then washed with 100 mL 2N HCl, 100 mL distilled water and dried over magnesium sulfate. The solvent was removed on a rotary evaporator and the resulting oil chromatographed (silica gel, methylene chloride) to afford 7.3 g (32.28 mmol, 50.4%) of an oil.
