Procedure

Combined 6-(4-(2,3-dimethoxypyridin-4-yl)-5-methoxy-1H-pyrazol-1-yl)-N-((tetrahydro-2H-pyran-4-yl)methyl)nicotinamide (0.029 g, 0.064 mmol) and lithium chloride (0.014 g, 0.320 mmol) in DMA (0.639 mL) and heated at 50° C. for 16 hours. The reaction mixture was purified by preparative HPLC (SunFire™ C18, 5 μm, ID 30 mm×75 mm) eluting with ACN (with 0.1% ammonium hydroxide) in water (with 0.1% ammonium hydroxide) to give the title compound (7.3 mg, 26.0%). 1H NMR (400 MHz, DMSO-d6) δ 1.05-1.23 (m, 2H) 1.49-1.58 (m, 2H) 1.74 (ttt, J=11.1, 11.1, 7.3, 7.3, 3.7, 3.7 Hz, 1H) 2.01 (s, 1H) 3.08-3.13 (m, 3H) 3.63 (s, 3H) 3.77 (d, J=2.8 Hz, 1H) 3.80 (s, 4H) 7.07 (br. s., 1H) 7.63 (d, J=5.3 Hz, 1H) 8.04-8.09 (m, 2H) 8.19 (dd, J=8.8, 2.3 Hz, 1H) 8.45 (d, J=8.8 Hz, 1H) 8.53 (t, J=5.8 Hz, 1H) 8.78 (d, J=2.0 Hz, 1H). MS m/z [M+H]+ 440.5.
