Reaction Steps
3,4-Dihydroxytoluene (1.686 g, 13.58 mM) was dissolved in 40 ml of ether and, using 2.748 g of triethylamine and 2.022 g of methyl dichlorophosphate, the reaction mixture was treated in the same manner as in Reference Example 5. There was obtained 2,400 g (88.4% yield) of 2-methoxy-5-methyl-2-oxo-1,3,2-benzodioxaphosphole as a viscous oil.
