[00249] 5A: l-(isoquinolin-5-yl)-4-methylpiperazin-2-one: To 5-bromoisoquinoline (1.657 g, 7.96 mmol) and 4-methylpiperazin-2-one (1, 8.76 mmol) was added DMSO (7 mL), 1,10-phenanthroline (0.144 g, 0.796 mmol), potassium carbonate (3.30 g, 23.89 mmol) and the mixture was degassed with Ar for 30 min. Copper(I)iodide (1.213 g, 6.37 mmol) was added and the reaction was heated in oil bath at 130 C overnight. The reaction was cooled to room temperature and quenched with NH4OH (10 mL) and water (20 mL) and diluted with EtOAc. The aqueous layer was extracted EtOAc (2 x 50 mL) and then, nBuOH (lx 30 mL). Combined organic layers were washed with brine and dried (MgS04). Purification by silica gel chromatography afforded 1.5g ( 78%) yellow solid. MS (ESI) m/z: 242.0 (M+H)+.
34770-60-0, The synthetic route of 34770-60-0 has been constantly updated, and we look forward to future research findings.
