Versuchsvorschrift

A suspension of [6-(5-amino-3-methyl-pyrazol-1-yl)-pyrimidin-4-yl]-methyl-amine (17 mg, 0.083 mmol), N-[5-(1-fluoro-1-methyl-ethyl)-pyridin-3-yl]-3-iodo-4-methyl-benzamide (41 mg, 0.104 mmol), Pd(OAc)2 (2 mg, 0.009 mmol), Xantphos (9 mg, 0.0166 mmol) and Cs2CO3 (54 mg, 0.166 mmol) in anhydrous 1,4-dioxane (2 mL) in a pressure vial was degassed by a stream of argon and sealed. The reaction was stirred at 150° C. for 1 hour. LCMS showed completion of the reaction. A solution of 5% diethyl dithiocarbomic acid sodium salt (3 mL) was added to the reaction. A light yellow precipitate was collected by filtration, washed with water and dried. The crude was purified by column (SiO2, EtOAc/hexanes: 30 to 100%) to give a white solid (25 mg, 64%): m/z 475.2 (M+1).
