Reaction Steps

A 2.0˜5.0 mL process vial was charged with 50 mg methanesulfonic acid 3-(1-methanesulfonyl-5-methyl-1H-pyrazol-3-ylamino)-6-methoxy-isoquinolin-1-ylmethyl ester, 50 mg piperidine, 75 mg K2CO3 in 3 mL THF/EtOH(1:1). The vial was heated at 120° C. for 30 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 in MeOH was sent to prep-HPLC to get 5 mg of (6-Methoxy-1-piperidin-1-ylmethyl-isoquinolin-3-yl)-(5-methyl-1H-pyrazol-3-yl)-amine as a yellow solid. LC-MS m/e 352 (MH+).
