Triethylamine → (S)-[1-(2-Benzyloxy-5-cyano-1,3-dioxo-2,3-dihydro-1H-benzo[de]isoquinolin-6-yl)-pyrrolidin-3-yl]-carbamic acid, tert-butyl ester

Participants

Reaction Steps

Following the procedure of Example B2, 2-benzyloxy-6-chloro-5-cyano-benzo[de]isoquinoline-1,3-dione (0.20 g, 0.55 mmol, from Example A2), (S)-pyrrolidin-3-yl-carbamic acid tert-butyl ester (0.11 g, 0.60 mmol), triethyl amine (0.11 g, 1.1 mmol) were reacted at ambient temperature for 5 hours. Column chromatography of the crude product on silica using chloroform/methanol (20:1) gave 0.18 g of the title compound.
