891785-28-7, 6-Bromo-3-fluoroisoquinoline: To a mixture of 6-bromoisoquinolin-3- amine (0.710 g, 3.18 mmol) in pyridine hydrofluoride (10.0 mL, 3.18 mmol, Aldrich) at – 78 0C was carefully added sodium nitrite (0.264 g, 3.82 mmol, Aldrich). The reaction mixture was stirred at -78 0C for 5 minutes. The reaction mixture was then warmed to room temperature and stirred for 40 minutes. The mixture was then poured into an ice bath and the pH was adjusted to >;9 with Na2CO3. The mixture was filtered to recover a yellow-purple solid. The solid was dissolved in EtO Ac-water with stirring. The resulting mixture was then extracted with EtOAc (3 x 200 mL). The EtOAc layers were combined, washed with brine, dried over Na2SOzI, filtered and concentrated. The residue was taken up in DCM-MeOH and adsorbed onto silica gel. Purification by chromatography on silica gel (eluting with EtOAc O – 7 % in hexanes) provided 6-bromo- 3-fluoroisoquinoline (500 mg, 70 %). LCMS (API-ES) m/z: 226.0, 228.0 [M+H]+.
