Participants

Reaction Steps

5.2 mg (0.130 mmol, 1.05 equiv) sodium hybride, 60% oil dispersion, were added to a room temperature solution of 50 mg (0.124 mmol, 1.0 equiv) 1-cyclopentyl-3-ethyl-1H-indazole-6-carboxylic acid (3,5-dichlor-pyridin-4-yl)-amide in 3 mL anhydrous DMF. After 30 min. 7.7 μl (0.124 mmol, 1.0 equiv) iodomethane were added and the mixture stirred at room temperature for 4 h. The reaction mixture was diluted with 50 mL H2O and extracted 2×20 mL ethyl acetate. The ethyl acetate extracts were combined, washed 2×5 mL H2O, 1×5 mL brine, and dried over Na2SO4. Filtration, concentration of filtrate and drying gave a yellow oil, which was purified on a silica gel column (25% ethylacetate/hexanes, flash) to give 27 mg (52%) of a white crystalline solid: mp 118-119° C.; HRMS calcd for C21H22N4OCl3+H: 417.12519. Found: 417.12270.
