To a microwave vial containing 5-bromo-1-chloroisoquinoline (Step 3, 0.300 g, 1.2 mmol), dissolved in pyridine (3 mL), was added Dimethylaminopropyl-amine (0.16 mL, 1.3 mmol). The mixture was placed into CEM Microwave for 8 minutes at 100° C., while supplying 80 Watts of power via power-max. The mixture was diluted with DCM and water, and extracted with DCM (3×10 mL). Then dried organics (over sodium sulfate) was filtered, and concentrated in-vacuo. It was then purified by Amino-Propyl Silica-gel chromatography in MeOH/DCM. This gave tan colored oil, which was titled product (0.085 g, 0.3 mmol). MS (ESI pos. ion) m/z: 309; 310 (M+H). Calc'd Exact Mass for C14H18N3Br: 308
