실험 절차
A solution of 5,6-dihydro-4H-imidazo[4,5,1-ij]-quinoline-2(1H)-thione (2.02 g, 11.6 mmol) in ethanol (25 ml) and 1N-sodium hydroxide was treated with 2-(chloromethyl)quinoline hydrochloride (2.48 g, 11.6 mmol) heated to reflux, cooled to room temperature, and the ethanol removed by evaporation in vacuo. The aqueous mixture was filtered and the precipitate washed with water (5×50 ml), dried in vacuo, and recrystallised from cyclohexane - EtOAc to give 5,6-dihydro-2-(quinolin-2-ylmethylthio)-4H-imidazo[4,5,1-ij]quinoline (2.13 g, 55%) as yellow crystals mp 125°-126° C. (Found: C, 72.8; H, 5.3; N,12.4 C20H17N3S requires C, 72.5; H, 5.2; N, 12.7%).
