Procedure

To a solution of 1,1′-thiocarbonyldipyridin-2(1H)-one (1.35 g, 5.81 mmol) in dichloromethane (19 mL) at ambient temperature was added a mixture (2:1) of 6,7-dimethylisoquinolin-3-amine and 5,6-dimethylisoquinolin-3-amine (1.00 g, 5.81 mmol). The reaction mixture was placed into a preheated oil-bath and stirred at 40° C. for 18 h, then cooled, concentrated, and purified by silica gel chromatography (10-35% ethyl acetate in hexanes) to afford a mixture (2:1) of 3-isothiocyanato-6,7-dimethylisoquinoline and 3-isothiocyanato-5,6-dimethylisoquinoline (186 mg, 0.869 mmol, 15%) as a yellow solid. MS (LC/MS) R.T.=2.06; [M+H]+=215.1.
