To a suspension of pyridinium chlorochromate (3.65 g, 16.93 mM) in CH2Cl2 (20 ml) was added the alcohol 20, (3.02 g, 8.46 mM) in CH2Cl2 (15 ml). After stirring for 4 hours, the reaction solution was decanted from the chromium precipitates that were washed with EtOAc (2×150 ml). The reaction solution and the washes were combined, filtered through florosil, and concentrated in vacuo. Chromatography (120 g, Baker 40 gm silica gel) with Et2O:hexane (1:1 to 100% Et2O) as eluent, followed by crystallization from Et2O:hexane afforded 23, (2.09 g, 70%) as a white crystalline solid, mp=85°-86° C.
