Procedure

A solution of 4-[4-(2-ethyl-5,7-dimethyl-3H-imidazo[4,5-b]pyridin-3-ylmethyl)phenylamino]-1-[1-(tert-butoxycarbonyl)piperidin-4-ylcarbonyl]piperidine (0.311 g, 0.54 mmol) obtained in Step 1 in chloroform (5.0 mL) was added with a 4 mol/L hydrogen chloride-ethyl acetate solution (2.0 mL) followed by stirring at room temperature for 1 hour. The reaction mixture was added with a 2 mol/L aqueous sodium hydroxide solution to control the pH to 12 and extracted with chloroform three times. The organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The obtained crystals were added with diisopropyl ether followed by stirring under reflux for 1 hour. The crystals were collected by filtration and dried under reduced pressure to obtain Compound 147 (0.153 g, 0.32 mmol, 60%).
