A mixture of 3-allyl-2-thioxo-2,3-dihydro-1H-spiro[benzo[h]quinazoline-5,1′-cyclohexan]-4(6H)-one (5, 0.100 g, 0.295 mmol), beta-dimethylaminoethyl bromide hydrobromide (0.076 g, 0.325 mmol), potassium hydroxide (0.041 g, 0.739 mmol) in Ethanol (1.738 ml) was refluxed ON. To the cooled solution, water (1 ml) was added and the mixture was extracted with EtOAc 2×. The organics were washed with brine, dried over sodium sulfate, filtered, and concentrated. 1H NMR (500 MHz, DMSO-d6) δ ppm 8.12, 7.37-7.22, 5.95, 4.71, 3.48, 3.05, 2.76, 2.64-2.58, 2.36, 1.74-1.72, 1.59-1.53, 1.42-1.39; MS (EI) m/z 410 (M+1)
