Procedure
A mixture of 2.65 g (10.1 mmol) of triphenylphosphine and 20 ml of toluene is prepared and 2 ml (10.2 mmol) of DIAD (diisopropyl azodicarboxylate) are added at 0° C. The solution obtained is added to a solution of 1 g (8.4 mmol) of 4-hydroxybenzonitrile and 1.30 ml (10.2 mmol) of methyl 2,2-dimethyl-3--hydroxy-propanoate in 10 ml of toluene at 0° C. The reaction mixture is subsequently stirred for 30 min at 80° C. and then concentrated under reduced pressure. The crude product is purified by chromatography on silica gel using toluene as the eluent to give the expected compound in the form of a colorless oil (yield=89%).
