Procedure

6-Methoxy-3-(1H-pyrazol-3-ylamino)-2H-isoquinolin-1-one (4.7 g, 0.017 mol) and POCl3 (60 ml) were sealed in 3 different bottles (20 ml). The mixture was heated at 150° C. for 15 minutes under microwave irradiation. The mixture was concentrated, the residue was treated with 15 ml MeOH and stirred for 2 hours at room temperature. The solid was collected and dried to give product (3.4 g, 68% yield). LC-MS: 275 (MH+)
