5-Chloro-N-[5-[2-(3,5-dimethoxyphenyl)ethyl]-2H-pyrazol-3-yl]pyrazine-2-carboxamide (388 mg, 1.00 mmol) was added in one portion to 1,2-dimethyl-piperazine (228 mg, 2.00 mmol) in anhydrous dimethylsulfoxide (2.00 ml) at 25 C. The resulting solution was stirred at ambient temperature for 2 h. The residue was purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 7M NH3/MeOH to afford impure material. The concentrated eluent was purified by silica column chromatography, eluting with a gradient of 0 to 10% 7M NH3/MeOH in DCM. Pure fractions were evaporated to dryness to afford the title compound (375 mg, 81%) as a yellow solid. 1H NMR (399.9 MHz, DMSO-d6) delta 1.07-1.09 (3H, d), 2.06-2.20 (2H, m), 2.23 (3H, s), 2.76-2.86 (2H, m), 2.87 (4H, s), 3.13-3.19 (1H, m), 3.72 (6H, s), 4.27-4.30 (2H, m), 6.33 (1H, t), 6.42 (2H, d), 6.46 (1H, s), 8.35 (1H, d), 8.70 (1H, d), 9.75 (1H, s), 12.18 (1H, s).
