Triethylamine → (3-{[(6-Oxo-5,6-dihydro-phenanthridin-2-ylcarbamoyl)-methyl]-amino}-propyl)-carbamic acid tert-butyl ester

Participants

Reaction Steps

To a stirred suspension of 50 mg of 2-chloro-N-(6-oxo-5,6-dihydro-phenanthridin-2-yl)acetamide (XV) (0.17 mmol) in N,N-dimethylformamide (3 mL), 0.09 mL of (3-amino-propyl)-carbamic acid tert-butyl ester (0.51 mmol) and 0.036 mL of triethylamine (0.26 mmol) were added. The reaction mixture was stirred at room temperature overnight, evaporated to dryness and then purified through preparative HPLC on a Waters X Terra RP 18 (19×250 mm, 5 □m) column. Mobile phase A was 0.05% ammonia/acetonitrile:95/5 and mobile phase B was acetonitrile/water:95/5. Gradient from 10 to 75% B in 15 min. Fractions containing the desired compound were dried, affording 32 mg (44% yield) of the title compound.
