Reaction Steps

6-Bromo-1-oxo-4-phenyl-1,2-dihydroisoquinoline-3-carboxylic acid methyl ester (54 mg), 2-fluorobenzylbromide (34 mg) and 2-tert-butylimino-2-diethylamino-1,3-dimethyl-perhydro-1,3,2-diazaphosphorine resin (2.2 mmol/g, 110 mg) were suspended in dimethylformamide (2 ml), and the suspension was shaken at room temperature for 15 hr. using a shaking machine. After filtration, the solvent was evaporated under reduced pressure, and the obtained residue was purified by preparative HPLC to give the title compound (11 mg, 15%).
