A 0.5-2.0 mL process vial was charged with 1-(2,4-difluoro-phenyl)-3-(5-methyl-1H-pyrazol-3-ylamino)-isoquinolin-6-yl trifluoromethanesulfonate (24.3 mg), Pd(OAc)2 (2 mg), Mo(CO)6 (13.2 mg), morpholine (13.0 mg), 1,8-Diazabicyclo[5.4.0]undecen (DBU) (22.9 mg), and dry tetrahydrofuran (THF) (1 mL). The vial was immediately capped under air and heated at 150° C. for 15 min under microwave irradiation. After cooling, the reaction mixture was filtered through a short silica gel column, and the solvent was removed under reduced pressure. The residue was sent to prep-HPLC to get 5 mg of [1-(2,4-difluoro-phenyl)-3-(5-methyl-1H-pyrazol-3-ylamino)-isoquinolin-6-yl]-morpholin-4-yl-methanone as a yellow solid.
