Reaction Steps

Preparation of example 66 from the title compound of Example 7 (hydrochloride) (30 mg, 0.096 mmol), 2-ethylsulfanyl-nicotinic acid (22 mg, 0.12 mmol), triethylamine (0.020 mL, 0.14 mmol), and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (46 mg, 0.12 mmol) in CH2Cl2 (0.4 mL) and N,N-dimethylformamide (0.4 mL) was carried out analogously to Example 11. Silica gel chromatography (pre-rinsed silica with 3% triethylamine in ethyl acetate, eluted with 3% triethylamine in 19:6:1 ethyl acetate:hexane:methanol), also in an analogous manner, afforded the title compound (7 mg, 0.016 mmol) as a yellow powder in 17% yield.
