Reaction Steps
By the method of Example 1, Step B, 61.90 grams (0.279 mole) of 2,3-dichloro-5-nitrophenylmethanol and 26.41 grams (0.098 mole) of phosphorus tribromide were reacted in 800 mL of toluene, yielding 64.38 grams of 2,3-dichloro-5-nitrophenylmethyl bromide as a golden oil which solidified upon standing. The NMR spectrum was consistent with the proposed structure.
