86.63 mg diphenyl cyanocarbonimidate, 52.1 mg isoquinolin-6-amine, and 6 ml THF were added to a reaction bottle with thermal reflux for 3.5 hrs. After removing THF by vacuum, the residue was added to 10 ml EA. The precipitated solid was filtered to obtain 32.9 mg 1-cyano-3-(isoquinolin-6-yl)-2-phenylisourea. The intermediate was reacted with equivalent tert-butyl-2-(benzylamino)ethylcarbamate and 20 mg of DIPEA in 5 ml DMF at 110 C. for 18 hrs. After cooling, 1N NaOH was added and extracted twice with EA. After the combined EA layer was dried and concentrated by Na2SO4, 26.4 mg intermediate product was eluted out by a SiO2 column (EA/Hexane 4:1). The intermediate was added to 1.5 ml 6N HCl at room temperature with stirring overnight. After the reaction solution was evaporated under reduced pressure, 2 ml acetone/methanol (10:1) was added. The precipitate was filtered and washed with acetone, and then the solid was taken and evaporated in vacuum to give 18.7 mg of product.
