Reaction Steps

To a stirred solution of (S)-(5,5-dimethyltetrahydrofuran-2-yl)methanol (14 g, 108 mmol) and PPh3 (33.8 g, 129 mmol) in THF (140 ml) under N2 was added phthalimide (17.40 g, 118 mmol) to give a suspension. The mixture was cooled to 8° C. and DIAD (27.2 ml, 140 mmol) was added dropwise over 30 mins keeping internal T<10° C. The resulting white slurry was diluted with water (100 ml) and extracted with EtOAc (100 ml). The organics were washed with sat. NaHCO3 (100 ml), brine (100 ml) and dried (MgSO4) and concentrated under reduced pressure. Purification by chromatography on silica eluting with 0-20% EtOAc/iso-hexane afforded the title compound as a white crystalline solid;
