実験手順

2,5-Dichlorobenzothiazole (0.049 moles, 10.0 g), 4-aminothiophenol (0.049 moles, 6.1 g) and DMAP (0.049 moles, 6.0 g) were stirred for 3 days at room temperature in 250 ml ethanol, filtered, and concentrated. Ethyl acetate was added and the solution washed with water, dried over sodium sulfate and concentrated. The product was purified by HPLC over silica gel eluted with 25% ethyl acetate in hexane to yield 2-(4-aminophenylthio)-5-chlorobenzothiazole 3.2 g, 22%. Mass spec (FD) 292. Calculated for C13H9ClN2S2 : C, 53.33; H, 3.10; N, 9.57. Found: C, 53.03; H, 3.30; N, 9.70.
