Participants

Procedure

50 mg (0.114 mmol) of 4-ethoxy-3-(5-methyl-4-oxo-7-(1-ethylpropyl)-3,4-dihydro-imidazo[5,1-f][1,2,4]triazin-2-yl)-benzenesulphonyl chloride are initially charged in 5 ml of dichloromethane and a spatula tip of 4 dimethylaminopyridine is added, followed by 30 mg (0.342 mmol) of N-methylpiperazine. The mixture is stirred at room temperature overnight, diluted with dichloromethane, washed twice with saturated ammonium chloride solution, dried over sodium sulphate, concentrated and filtered through silica gel (methanol).
