Participants

Reaction Steps

To the pyridine (2 ml) solution of 4-(2-amino-6,6-dimethyl-11-oxo-6,11-dihydro-5H-benzo[b]carbazole-8-yl oxy)-piperidine-1-carboxylic acid tert-butyl ester (Compound P6, 50 mg, 0.105 mmol), mesyl chloride (9 μl, 1.2 eq.) was added and stirred at room temperature for 30 min. Upon the completion of the reaction, the reaction solution was concentrated under reduced pressure to obtain the title compound as an unpurified product.
