実験手順

To a solution of ethyl 5-cyclopropylnicotinimidate (0.2 g, 1.04 mmol) in ethanol was added acetic acid (0.1 mL), triethylamine (0.1 mL) and a solution of (R)-(1-(5,6-diaminopyridin-2-yl)piperidin-3-yl)(pyrrolidin-1-yl)methanone dihydrochloride salt (0.4 g, 1.1 mmol) in ethanol. The reaction mixture was heated at reflux for 24 h. The solvent was removed under reduced pressure and to the resulting residue was added a saturated aqueous solution of ammonium chloride. The mixture was extracted with ethyl acetate. The organic layer was concentrated under reduced pressure. The crude material was purified via preparative TLC to afford the title compound (0.025 g). 1H NMR (400 MHz, DMSO-d6) δ 0.85 (br s, 2H), 1.07 (d, 2H), 1.47-1.74 (m, 4H), 1.74-1.96 (m, 5H), 1.98-2.10 (m, 1H), 2.61 (br s, 2H), 2.92 (d, 2H), 3.41-3.59 (m, 2H), 4.33 (d, 1H), 4.39 (d, 1H), 6.86 (d, 1H), 7.81 (d, 1H), 8.00 (br s, 1H), 8.47 (br s, 1H), 9.05 (br s, 1H), 13.07 (br s, 1H). MS (ES+) (M+H) 417.36; LCMS retention time 3.03 min (Method S).
