Reaction Steps

A mixture of 2,6-dichlorobenzothiazole (0.71 g, 3.5 mmol) and 4-bromoaniline (0.61 g, 3.5 mmol) in n-butanol (6 mL) was heated at 60-70° C. under nitrogen to obtain a solution, to which 4 M HCl in dioxane (0.43 mL, 1.73 mmol) was then slowly added dropwise. The reaction mixture was then heated at 90° C. for 18 h. Upon cooling to rt, the reaction mixture was concentrated under reduced pressure. The resulting solid was triturated with ethanol and collected by filtration. This yielded 1.09 g (93%) of the title compound. LC/MS m/z 339 (MH+); retention time 3.98 min. 1H NMR (CD3OD) δ 7.31 (d, 1H), 7.42-7.58 (m, 5H), 7.61 (d, 1H).
