실험 절차

Using the General N-Alkylation Procedure: To a stirred solution of N′-(1H-benzimidazol-2-ylmethyl)-N′-(5,6,7,8-tetrahydro-8-quinolinyl)-1,4-benzenedimethanamine (128 mg, 0.32 mmol) and triethylamine (100 ul, 0.72 mmol) in THF (5 mL) was added 2-chlorobenzoxazole (50 uL, 0.44 mmol) and the mixture was stirred at reflux for 16 h. Purification of the crude material by radial chromatography on silica gel (1 mm plate, CH2Cl2/MeOH/NH4OH, 125:1:1) afforded the desired amine (83 mg, 37%) as a yellow foam.
