Reaction Steps

Preparation of example 22 from the title compound of Example 7 (hydrochloride) (21 mg, 0.076 mmol), nicotinic acid (7 mg, 0.076 mmol), triethylamine (0.014 mL, 0.10 mmol), and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (32 mg, 0.084 mmol) in CH2Cl2 (0.3 mL) and N,N-dimethylformamide (0.3 mL) was carried out analogously to Example 11. Silica gel chromatography (9:1 CH2Cl2:methanol), also in an analogous manner, afforded the title compound (20 mg, 0.052 mmol) as a yellow powder in 69% yield.
