Reaction Steps

A solution of 4.913 g (17.41 mmol) of [2-(2-trifluoromethylbenzyloxy)phenyl]methanol from Example 80A in 70 ml of acetonitrile is mixed with 5.675 g (16.54 mmol) of triphenylphosphonium hydrobromide and heated to reflux for 3 hours. The reaction solution is then concentrated to dryness, and the resulting oil is taken up and triturated in diethyl ether. The product crystallizes as a white solid during this. After filtration, the solid is dried in a drying oven at 50° C. overnight. 9.621 g (88% yield) of crystalline product are obtained.
