Reaction Steps

Trifluoro-methanesulfonic acid 5-cyano-6-cyanomethylsulfanyl-4-propyl-pyridin-2-yl ester (1.10 g, 3.00 mmol) (see Example 1, Method B) and 4-hydroxypiperidine (310 mg, 3.00 mmol) was suspended in 2 mL of dioxane. Triethylamine (0.84 mL, 6.0 mmol) was added and the reaction mixture was heated in a SmithSynthesizer™ (Personal Chemistry) at 100° C. for 2 h. This reaction mixture was poured into water and the resulting solid was collected by filtration and air dried to provide 3-amino-6-(4-hydroxy-piperidin-1-yl)-4-propyl-thieno[2,3-b]pyridine-2-carbonitrile (845 mg, 89%).
