Procedure

A stirred solution of the product from Step E (2.880 grams) in dry DMF (30 mL) was treated with allyl bromide (1.282 mL) followed by cesium carbonate (4.828 grams). After 2 hours, the mixture was partitioned between isopropyl acetate and pH4 pthalate buffer. The organic was washed twice with water, dried over magnesium sulfate and filtered. Concentration gave the title compound in such purity that further processing was not required.
