실험 절차

A solution of 1-(2-bromobenzo[d]thiazol-6-yl)-1-(1H-imidazol-1-yl)-N,N-dimethyl-butan-2-amine (30 mg, 0.079 mmol), methyl-4-aminobenzoate (24 mg, 0.16 mmol) in 300 μL DCE and 300 μL n-BuOH was treated with 4N HCl (40 μL, 0.16 mmol) and refluxed overnight. The mixture was then partitioned between DCM and saturated NaHCO3 and the aqueous phase was extracted with DCM. The combined organic extracts were dried over Na2SO4, decanted and concentrated in vacuo. The residue was purified by PTLC using two 1 mm silica plates eluting with 5% MeOH (2N NH3)/DCM to provide methyl-4-((6-(2-(dimethylamino)-1-(1H-imidazol-1-yl)butyl)benzo[d]thiazol-2-yl)amino)benzoate. MS (ESI+) m/z 450.19 [M+H]
