Reaction Conditions

Reaction Steps

Dibenzyl phosphite (1.70 mL, 7.63 mmol) was added to a stirred suspension of sodium hydride (60% dispersion in mineral oil) (0.381 g, 9.53 mmol) in dry DMF (11.4 mL) at 25° C. under N2. After 15 min 2-(3-bromopropoxy)tetrahydro-2H-pyran (1.29 mL, 7.63 mmol) was added and the mixture was stirred at 25° C. for 5 h. The reaction mixture was diluted with water (20 mL) and extracted with Et2O (2×40 mL). The combined organic extracts were washed with brine (20 mL), dried (Na2SO4) and concentrated in vacuo to afford dibenzyl [3-(tetrahydro-2H-pyran-2-yloxy)propyl]phosphonate. Rf=0.06 (20% EtOAc/hexanes). LCMS calc.=427.17; found=427.15 (M+Na)+.
