実験手順

2-Chlorobenzothiazole (0.06 moles, 10.1 g), 4-aminothiophenol (0.06 moles, 7.5 g) and potassium carbonate (0.06 moles, 8.3 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 40-60% ethyl acetate in hexane to yield 2-(4-aminophenylthio)benzothiazole 13.7 g, 88%. Mass spec (FD) 258. Calculated for C11H10N2S2 : C, 60.44; H, 3.90; N, 10.84. Found: C, 60.63; H, 3.98; N, 11.01.
