Reaction Steps

A suspension of 2-(2-(2-(2-((1-(piperidin-4-yl)-1H-pyrazol-4-yl)amino)-5-(trifluoromethyl)pyrimidin-4-yl)ethyl)phenyl)propanamide A67 (80 mg, 0.16 mmol), 2-iodopropane (25 μL, 0.25 mmol) and K2CO3 (68 mg, 0.49 mmol) in MeCN (5 mL) was irradiated in the microwave at 120° C. for 40 minutes. Additional 2-iodopropane (25 μL, 0.25 mmol) was added and the reaction mixture was irradiated in the microwave at 120° C. for another 40 minutes. Upon cooling, the liquid was decanted from the solid and the volatiles were removed in vacuo. The resultant solid was suspended in water (50 mL) and sonicated for 10 minutes before being filtered. The solid was dissolved in acetone (3 mL) and precipitated by the addition of petroleum benzine 40-60° C. before being collected by filtration and dried under high vacuum to give the title compound 60 as a tan solid (61 mg, 70%). LCMS-D: rt 3.060 min; m/z 530.4 [M+H]+.
