Reaction Steps

To a sealed tube was added trifluoro-methanesulfonic acid 6-carbamoylmethylsulfanyl-5-cyano-4-propyl-pyridin-2-yl ester (66.7 mg, 0.174 mmol) in 4 mL of dry DMF, followed by the addition of 1-(piperidin-4-ylamino)-3-(pyridin-4-yloxy)-propan-2-ol trihydrochloride salt (69 mg, 0.191 mmol) and N-N-diisopropylethylamine (180 mg, 1.39 mmol). The reaction mixture was stirred at 70° C. for 2 h. DMF was removed in vacuo. The residue was dissolved in 5 mL of MeOH, followed by the addition of sodium methoxide, 0.5 M solution in MeOH (1.74 mL, 0.86 mmol). The reaction mixture was stirred at 70° C. for 2 h. The reaction mixture was concentrated in vacuo. The residue was loaded onto a flash chromatography column. The column was eluted with 0–5% 2M NH3 in MeOH/CH2Cl2. The product fractions were collected, concentrated and dried under high vacuum pump to afford 24 mg (28.5%) of the title compound as a light brown solid product. (TLC: Rf=0.4, 5% 2M NH3 in MeOH/CH2Cl2, UV). ES+ 485.29 m/z (MH+)
