Reaction Steps

Sodium hydride (1.6 equiv., 1.029 mmol, 0.041 g (60%)) was added to a solution of 86 (1.0 equiv., 0.643 mmol, 0.302 g) in DMF (15 ml), the reaction mixture was stirred for 1 h at room temperature. Methyl iodide (1.2 equiv., 0.772 mmol, 0.110 g) was added and the mixture was stirred at room temperature for 24 h. Water was added to the reaction mixture, and the formed precipitate was filtered off and washed with water and isopropyl ether to give N-[5,6-dihydro-6-(4-nitrophenyl)-5-oxo-pyrido[2′,1′:2,3]-imidazo[4,5-c]isoquinolin-9-yl]-N-methyl-hexanamide (87) (0.296 g, yield=95%, purity (LC)=93%).
