Procedure

Compound 6f (2 g, 6.7 mmol) in 35 mL of DMF was treated with HATU (2.5 g, 6.7 mmol), diethylamine (0.2 mL, 8.7 mmol), and diisopropylethylamine (4.75 mL, 26.8 mmol). After stirring for 3 h the reaction was poured into water and the solid was collected to give the product, compound 7f. The filtrate was extracted with diethyl ether/THF (1:1). The combined organic phases were washed with water, brine, and dried over magnesium sulfate. The solvent was evaporated in vacuo and combined with the above solid to give 1.5 g total of compound 7f. MS m/z=353 (M+1).
