Procedure
To a solution of 2-chlorobenzyl alcohol (1.0 g, 7.0 mmol) in diethyl ether (15 ml) at 0° C. was added N,N-diisopropylethyl amine (2.4 ml, 14.0 mmol), and phosgene solution in toluene (7.5 ml, 14.0 mmol). The mixture was allowed to warm up to room temperature in 2 h while stirring, then it was filtered. The diethyl ether was removed by rotary evaporator, and the solution of 2-chlorobenzyl chloroformate in toluene was carried on for the next step reaction.
