A mixture of 332.2 mg (1.47 mmol) of the diol from Step H, 243.5 mg (1.61 mmol) of t-butyldimethylchlorosilane, and 120 mg (1.76 mmol) of imidazole in 8 mL of sieve dried DMF was stirred at 100° C. for 45 minutes. The mixture was partitioned between EtOAc, ice-water and 2N HCl, and the organic phase was separated, washed twice with ice-water, and then with brine, dried over Na2SO4, filtered, evaporated, and dried in vacuo. Purification by PLC using CH2Cl2-EtOAc (50:1) gave 447.4 mg of the title material.
