실험 절차

2-Benzyloxy-6-chloro-1-oxo-4-phenyl-1,2-dihydroisoquinoline-3-carboxylic acid (240 mg) was dissolved in THF (4.8 ml), and oxalyl chloride (100 μl) and DMF (1 drop) were added at 0° C. with stirring. The mixture was stirred at room temperature for 2 hrs. and concentrated under reduced pressure. Toluene was added to the residue and they were boiled together several times to give 2-benzyloxy-6-chloro-1-oxo-4-phenyl-1,2-dihydroisoquinoline-3-carbonyl chloride.
