Procedure

A solution of 2-(3-Hydroxyphenyl)acetonitrile (Step A, 5 g, 37 mmol) and diisopropyl azodicarboxylate (DIAD, 3.38 g, 16.7 mmol) in dry THF (20 ml) was added drop wise to a solution of 2,6-Dimethylbenzyl alcohol (2.25 g, 16.5 mmol) and triphenylphosphine (TPP, 4.3 g, 16.4 mmol) in THF (30 ml) at 0° C. under argon. The reaction mixture was stirred at room temperature for 16 hours or until all the starting material is consumed. Silica gel (25 g) was added to the mixture, solvents were removed under reduced pressure, loaded on silica gel column and eluted with methylene chloride:hexane (1:1) to give light yellow crystalline solid.
