Mode opératoire

The tetrabutylammonium salt of bis-tert butyl phosphate (45.1 g, 0.1 mol) and chloroiodomethane (200 g, 1.14 mol) were combined in 100 ml of benzene and the mixture was stirred at room temperature for four hours and then the benzene was removed under vacuum. A portion of 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 the volitiles on a vacuum pump provided di-tert-butyl chloromethyl phosphate, as a light yellow or light brown oil which was utilized in the next step without further purification.
