الإجراء التجريبي
To a solution of 4-(5-chloropyridin-3-yl)-3-[(trans-4-methylcyclohexyl)methyl]-2-[(3R)-3-phenylmorpholin-4-yl]-3H-imidazo[4,5-c]pyridine-6-carboxylic acid (Example 3.22, prepared from Example 2.1, Step 4 using a procedure similar to that described for Example 1.1, Step 5; 50 mg, 0.09 mmol) in DMF (2.0 mL) were added HATU (15 mg, 0.11 mmol), DIPEA (0.03 mL, 0.18 mmol), and 2.0 M methylamine in MeOH (0.09 mL, 0.18 mmol) at room temperature. After being stirred for 2 hours, the reaction mixture was diluted with H2O (10 mL), the aqueous layer was extracted with EtOAc and then the organic layer was washed with water and brine, dried over anhydrous Na2SO4, filtered, and concentrated in vacuo. Purification of the residue on a silica gel column (0 to 10% MeOH/CH2Cl2) afforded 4-(5-chloropyridin-3-yl)-N-methyl-3-[(trans-4-methylcyclohexyl)methyl]-2-[(3R)-3-phenylmorpholin-4-yl]-3H-imidazo[4,5-c]pyridine-6-carboxamide. 1H NMR (300 MHz, CD3OD) δ 8.71 (d, J=2.1 Hz, 1H), 8.66 (s, 1H), 8.17-8.19 (m, 2H) 7.40-7.42 (m, 2H), 7.24-7.26 (m, 3H), 4.66-4.69 (m, 1H), 3.98-4.06 (m, 4H), 3.66-3.75 (m, 2H), 3.41-3.50 (m, 2H), 3.48 (s, 3H), 1.28-1.43 (m, 2H), 1.10-1.19 (m, 1H), 0.82-0.99 (m, 2H), 0.74 (d, J=6.3 Hz, 3H) 0.61-0.65 (m, 3H), 0.41-0.45 (m, 2H).
