Participants

Reaction Steps

To 3,6,6,-trimethyl-1,5,6,7-tetrahydro-indol-4-one (0.104 g, 1.2 eq) in dimethylacetamide (3 mL), sodium hydride (14.4 mg, 1.2 eq) is added slowly and stirred at RT for 0.5 h. Then 1-(1-amino-6-fluoro-isoquinolin-4-yl)-ethanone (0.1 g, 1 eq) is added and stirred at 150° C. overnight. The reaction mixture is poured into Sat'd NH4Cl aq. (200 mL), extracted by EtOAc (3×100 mL), dried over Na2SO4, filtered, concentrated to give a crude product. That is purified by Biotage chromatography, eluted by 50-100% EtOAc in Hexanes to give 1-(4-acetyl-1-amino-isoquinolin-6-yl)-3,6,6 trimethyl-1,5,6,7-tetrahydro-indol-4-one (48.1 mg, 27%). LC/MS m/z=362 [M+H]+.
