Water → 6-Octylbenzo[d]thiazol-2-amine

Participants

Reaction Steps

4-octylaniline (500 mg, 2.5 mmol), AcOH (4 mL), and KSCN (970 mg, 10 mmol) were stirred at r.t. for 10 min, and then a solution of bromine (0.13 mL, 2.5 mmol) in AcOH (2 mL) was added to the mixture over 20 min. The reaction mixture was stirred at r.t. for 8 h, then poured into cold water and extracted with EtOAc. The organic layer was purified by silica gel chromatography using PE/EA (3/1) to give compound the title compound (460 mg, 70%). 1H NMR (300 MHz, CDCl3) δ 7.446 (s, 1H), 7.320 (s, 1H), 7.230 (d, 1H), 2.577 (t, 2H), 1.567-1.506 (m, 2H), 1.266-1.167 (m, 10H), 0.847 (t, 3H).
