Reaction Steps
The intermediate phenoxy chloroformates are prepared by reaction of the appropriate phenoxyalcohol with excess phosgene in an inert solvent such as methylene chloride in the presence of a catalytic quantity of dimethyl formamide. The reaction is carried out at 20°-80° C. The solvent and excess phosgene is then removed under vacuo to give the desired intermediate phenoxy chloroformate.
