5-Isocyano-2,3-dihydroinden-1-one (6) (60.0 mg, 379 μmol) was combined with pyrazin-2-amine (12) (36.1 mg, 379 μmol), 1-methyl-1H-indole-3-carbaldehyde (15) (60.4 mg, 379 μmol) and Sc(OTf)3 (18.7 mg, 37.9 μmol) in DCM/MeOH and stirred at room temperature overnight. The solvent was evaporated and purified by silica using 2% MeOH/EtOAc to provide 5-(2-(1-methyl-1H-indol-3-yl)imidazo[1,2-a]pyrazin-3-ylamino)-2,3-dihydroinden-1-one (16). MS (APCI) m/z (M+1)
