Sodium hydride → HCID 25060728, compound

Participants

Reaction Steps

To 3,6,6,-trimethyl-1,5,6,7-tetrahydro-indol-4-one (0.41 g, 1.2 eq) in dimethylacetamide (50 mL) is added slowly sodium hydride (69.5 mg, 1.5 eq) and the resulting mixture is stirred at RT for 0.5 h. Then 7-Fluoro-quinazolin-2,4-diamine (0.342 g, 1 eq) is added and the mixture is stirred at 150° C. for overnight. The reaction mixture is poured into sat'd NaHCO3 aq. solution (300 mL), extracted by EtOAc (3×150 mL). The combined organic layers are dried over Na2SO4, filtered, concentrated. The crude product is purified by flash chromatography to give 1-(2,4-Diamino-quinazolin-7-yl)-3,6,6-trimethyl-1,5,6,7-tetrahydro-indol-4-one (0.5 g, 77.6% yield). LC/MS m/z=336 [M+H]+.
