반응 단계

A suspension of 4-Bromo-6-hydrazino-isoquinolin-1-ylamine (0.097 g, 0.38 mmol) and 2-acetyl-5,5-dimethyl-1,3-cyclohexanedione (0.074 g, 0.41 mmol) in EtOH/Acetic acid (3:1, 7 mL) is microwaved at 150° C. for 20 min. The solvent is evaporated and the residue is dried under vacuum. Purification of the crude material using a Biotage column (0-10% MeOH/CH2Cl2) afforded 0.1223 g (80%) of 1-(1-Amino-4-bromo-isoquinolin-6-yl)-3,6,6-trimethyl-1,5,6,7-tetrahydro-indazol-4-one. LC/MS m/z=400 [M+H]+.
