Combined 6-(4-(2-(dimethylamino)pyridin-4-yl)-5-methoxy-1H-pyrazol-1-yl)-N-((tetrahydro-2H-pyran-4-yl)methyl)nicotinamide from the above reaction and lithium chloride (42.7 mg, 1.008 mmol) and DMA (1 mL) and heated at 60° C. for 20 h. The reaction mixture was diluted with 0.2 mL DMSO and purified by prep HPLC (ammonium hydroxide conditions) to give the title compound (42 mg, 49.3% yield) as a yellow solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.12-1.28 (m, 2 H) 1.56-1.67 (m, 2 H) 1.81 (ddt, J=14.9, 7.5, 3.8, 3.8 Hz, 1 H) 3.05 (s, 6 H) 3.17 (t, J=6.4 Hz, 2 H) 3.28 (td, J=11.6, 1.8 Hz, 2 H) 3.86 (dd, J=11.4, 2.5 Hz, 2 H) 7.07 (d, J=4.5 Hz, 1 H) 7.35 (br. s., 1 H) 7.67 (d, J=6.1 Hz, 1 H) 7.90 (s, 1 H) 8.10-8.19 (m, 1 H) 8.47-8.59 (m, 2 H) 8.80 (d, J=2.0 Hz, 1 H).
