To a solution of 1-amino-4-bromo-6-fluoro-isoquinoline (0.029 g, 0.12 mmol) in DMF (1 mL) are added 3,6,6-Trimethyl-1,5,6,7-tetrahydro-indol-4-one (0.042 g, 0.24 mmol) and NaH (0.01 g, 0.24 mmol). The reaction mixture is microwaved at 120° C. for 40 min, cooled to RT, and treated with NH4Cl (satd. aq, 2 mL). The aqueous phase is extracted with EtOAc (2×). The combined organic layers are washed with brine, and dried over MgSO4. The solvent is evaporated and the residue is dried under vacuum. Purification of the crude material using a Biotage column (0-10% MeOH/CH2Cl2) affords 0.0118 g (25%) of 1-(1-Amino-4-bromo-isoquinolin-6-yl)-3,6,6-trimethyl-1,5,6,7-tetrahydro-indol-4-one. LC/MS m/z=399 [M+H]+.
