Reaction Steps
A mixture of 2-tert-butyl-4-chloromethyl-1,3-oxazole (10.42 g) and triethyl phosphite (19.94 g) was stirred at 160° C. for 16 hrs. Excess triethyl phosphite was evaporated under reduced pressure. The residue was subjected to silica gel column chromatography and eluted with ethyl acetate-hexane (1:1, v/v), ethyl acetate, then ethyl acetate-ethanol (10:1, v/v) to give diethyl [(2-tert-butyl-1,3-oxazol-4-yl)methyl]phosphonate as a colorless oil (16.51 g, yield 100%).
