Mode opératoire

2-Chloro-6-methoxyquinoline (52.0 mmoles, 10.0 g), 4-aminothiophenol (52.0 mmoles, 6.5 g) and dimethylaminopyridine (52.0 mmoles, 6.3 g) were stirred for 16 hr in 250 ml ethanol. The reaction was condensed and purified by HPLC over silica gel eluted with 25-30% ethyl acetate/hexane to yield 2-(4-aminophenylthio)-6-methoxyquinoline. 8.5 g, 58% product. Mass spec (FD) 282. Calculated for C16H14N2OS: C, 68.06; H, 5.00, N, 9.92. Found: C, 68.04; H, 4.97; N, 10.02.
