Procedure

Vinyl chloroformate (3.0 g, 0.028 mol) and benzaldehyde (4.14 g. 0.039 mol) were dissolved in 1,2-dichloroethane (30 ml) and pyridine (0.1 g, 1.28 mol) was added dropwise to the stired solution. The solution was stirred for 1 day at 80° C., washed with water (25 ml), and the aqueous phase was back extracted with methylene chloride (25 ml). The combined organic phases were dried (MgSO4) and concentrated to give 3.0 g (50%) of the title product.
