Vorschrift

A mixture of tetrabutylammonium di-tert-butyl phosphate (57 g, 0.126 mol, Digital Specialty Chemicals) and chloroiodomethane (221 g, 1.26 mol) was stirred at room temperature for four hours before the volatiles were removed under vacuum. 500 ml of ethyl ether was added to the residue and insoluble solid was filtered away. Concentration of the filtrate in vacuo and removal of remaining volatiles using a vacuum pump provided di-tert-butyl chloromethyl phosphate as a light brown or yellow oil, which was utilized in the next step without further purification.
