実験手順
To the title product of Step F in 300 ml of CH2Cl2 at 0° C., triethylamine (6.17 g, 60.96 mmol) was added and stirred for 5 minutes. To the mixture, t-butylacetyl chloride (3.98 g, 29.57 mmol) was added dropwise over 10 minutes. The reaction mixture was stirred at 0° C. for 10 minutes and at room temperature for 1 hr. 100 ml 10% aqueous NaHSO4 was added. The aqueous layer was extracted with 100 ml CH2Cl2. The combined organic extracts were washed with 100 ml H2O, 50 ml brine, dried and concentrated. The residue was chromatographed on silica gel using 60:40:1 hexane/EtOAc/AcOH to provide the title product of this Example (13.10 g, 80% for two steps) as a white solid. melting point=120-128° C. (amorphous).
