Participants

Reaction Steps

A solution of PPh3 (42.8 g, 163.2 mmol) and 1-bromo-3-methoxypropane (25 g, 163.3 mmol) in toluene (70 mL) is heated at 150° C. in an autoclave for 44 h. After completion of the reaction, the mixture is filtered and the precipitate washed with toluene and dried under high vacuum for 4 h affording the title compound as a white powder. Rt (HPLC, Nucleosil C18, 10:90-100:0 CH3CN/H2O+0.1% TFA within 5 min, then 100% CH3CN+0.1% TFA): 5.06 min.
