실험 절차

1-methyl-1,4-diazepane (0.20 ml, 1.60 mmol) was added to 5-chloro-N-[5-[2-(3,5-dimethoxyphenyl)ethyl]-2H-pyrazol-3-yl]pyrazine-2-carboxamide (310 mg, 0.80 mmol) in DMSO (4.00 ml) at 25° C. The resulting solution was stirred at room temperature for 1 h. The reaction mixture was diluted with MeOH (5 ml) and the crude product was purified by ion exchange chromatography, using a SCX column. The desired product was eluted from the column using 7M NH3/MeOH and fractions were evaporated to dryness to afford crude product as an orange dry film. The crude product was purified by preparative HPLC, using decreasingly polar mixtures of water (containing 1% NH3) and MeCN as eluents. Fractions containing the desired compound were evaporated to dryness to afford the title compound (296 mg, 79%) as a white solid.
