Procedure

To a solution of product from Step E (2.1 g, 3.74 mmol) in methylene chloride (20 mL) was added trifluoroacetic acid (4 mL). The resulting solution was stirred for 2 hours, then poured onto saturated aqueous sodium bicarbonate, and extracted with methylene chloride (3×50 mL). The combined organic layers were dried over magnesium sulfate, filtered, and concentrated in vacuo to provide the title product without further purification.
