Participants

Reaction Steps

In a reactor cooled to +5° C., there are introduced 600 ml of dicloromethane, 43.7 g (0.59 mole) of tert-butanol and 94.7 g (0.66 mole) of α-chloroethyl chloroformate. 57 g (0.72 mole) of pyridine are then added dropwise and with stirring while the temperature is maintained at between 10° and 20° C. The mixture is stirred for 4 hours at room temperature.
