実験手順
5-Chloro-1-methyl-1H-pyrazole-4-carbonyl chloride (1.0 g, 5.6 mmol) was dissolved in CH2Cl2 (100 mL) under N2 and cooled to 0° C. 4-t-Butylaniline was added and the reaction was stirred with gradual warming to RT overnight. The reaction was quenched with saturated NaHCO3(aq) and extracted 3× with fresh CH2Cl2. The CH2Cl2 extracts were washed with brine, combined, dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure giving 5-chloro-1-methyl-1H-pyrazole-4-carboxylic acid (4-tert-butyl-phenyl)-amide as a foamy pink solid.
