Sodium hydride → HCID 25060727, compound

Participants

Reaction Steps

To 3,6,6,-trimethyl-1,5,6,7-tetrahydro-indol-4-one (0.3 g, 1.2 eq) in dimethylacetamide (50 mL) is added slowly sodium hydride (50.8 mg, 1.5 eq). The resulting mixture is stirred at RT for 0.5 h. To that 7-Fluoro-2-methyl-quinazolin-4-ylamine (0.25 g, 1 eq) is added and the mixture is stirred at 150° C. for overnight. The mixture is poured into sat'd NaHCO3 aq. solution (300 mL), and extracted by EtOAc (3×100 mL). The combined organic layers are dried over Na2SO4, filtered, concentrated. The crude product is purified by flash chromatography, eluted by 50% EtOAc in Hexane to EtOAc to give 1-(4-Amino-2-methyl-quinazolin-7-yl)-3,6,6-trimethyl-1,5,6,7-tetrahydro-indol-4-one (0.135 g, 29% yield). LC/MS m/z=335 [M+H]+.
