Reaction Steps

Preparation of example 14 from the title compound of Example 7 (15 mg, 0.054 mmol), 2-methyl-nicotinic acid (9 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 N,N-dimethylformamide (1.0 mL) was carried out analogously to Example 11. Silica gel chromatography (ethyl acetate), also in an analogous manner, followed by diethyl ether trituration afforded the title compound (7 mg, 0.018 mmol) as a yellow powder in 33% yield.
