Reaction Steps

Preparation of example 13 from the title compound of Example 7 (15 mg, 0.054 mmol), cyclopentyl-acetic acid (8 mg, 0.062 mmol), triethylamine (0.030 mL, 0.22 mmol), and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (25 mg, 0.065 mmol) in dimethylformamide (1.0 mL) was carried out analogously to Example 11. Silica gel chromatography (1:1 ethyl acetate:hexane), also in an analogous manner, followed by diethyl ether trituration afforded the title compound (3 mg, 0.008 mmol) as a yellow powder in 14% yield.
