Reaction Steps

The title compound was prepared in the same manner as described for intermediate 56 using 1-cyclopentyl-6-cyclopropyl-3-methyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylic acid (160 mg, 0.561 mmol), 3-(aminomethyl)-4,6-dimethyl-2(1H)-pyridinone (119 mg, 0.785 mmol), 1-hydroxy-7-azabenzotriazole (153 mg, 1.121 mmol), EDC (215 mg, 1.121 mmol), N-methylmorpholine (0.247 mL, 2.243 mmol) and DMSO(10 mL). The final product was collected as 0.205 g (87%). LCMS E-S (M+H)=420.0. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.03 (d, J=6.06 Hz, 4 H), 1.85 (dd, J=9.35, 5.05 Hz, 3 H), 2.12 (s, 4 H), 2.16-2.28 (m, 6 H), 2.30-2.44 (m, 7 H), 2.63 (d, J=19.96 Hz, 3 H), 4.34 (d, J=4.29 Hz, 2 H), 5.31 (t, J=8.34 Hz, 1 H), 5.87 (s, 1 H), 7.01 (s, 1 H), 8.59 (br. s., 1 H), 11.52 (br. s., 1 H).
