실험 절차

A suspension of 1-(2-(2-(2,5-dichloropyrimidin-4-yl)ethyl)phenyl)cyclopropanecarboxamide A14 (263 mg, 0.781 mmol), Cs2CO3 (509 mg, 1.56 mmol) and a mixture of tert-butyl 3-amino-5-methyl-1H-pyrazole-1-carboxylate and tert-butyl 5-amino-3-methyl-1H-pyrazole-1-carboxylate A27 (154 mg, 0.781 mmol) in 1,4-dioxane (5 mL) was sonicated for 10 minutes. Xantphos (23 mg, 0.039 mmol) and Pd2(dba)3 (36 mg, 0.039 mmol) were added and the mixture was irradiated in the microwave at 120° C. for 20 minutes. The resulting mixture was adsorbed onto silica gel and purified by column chromatography (Biotage Isolera, 40 g SiO2 cartridge, 0-100% EtOAc in petroleum benzine 40-60° C.) to give a yellow oil which was dissolved in DCM (5.0 mL). TFA (1.0 mL) was added and the mixture was stirred at room temperature for 2 hours before the addition of sat. aq. Na2CO3 (20 mL) and water (100 mL). The resultant precipitate was collected by filtration, adsorbed onto silica gel and purified by silica gel column chromatography (Biotage Isolera, 12 g SiO2 cartridge, 0-100% EtOAc in petroleum benzine 40-60° C. then 0-30% MeOH in EtOAc) to give the title compound 27 as a yellow solid (8 mg, 3%). LCMS-A: rt 5.412 min; m/z 397.2 [M+H]+.
