Reaction Conditions

Reaction Steps

3-Chloro-5-(hydroxymethyl)benzonitrile (25 g, 145 mmol) was dissolved in THF (200 mL). The resulting yellow solution was cooled to 10° C. in an ice bath and treated dropwise with phosgene in toluene (152 mL, 289 mmol). The reaction mixture was stirred at ambient temperature for 16 hrs. The mixture was concentrated under reduced pressure and the crude material was diluted with toluene (200 ml) and re-concentrated under reduced pressure. The residue was purified by chromatography on silica (Redisep 340 g column on a Biotage system), eluting with EtOAc/iso-hexane to give 3-chloro-5-cyanobenzyl carbonochloridate as an oil.
