실험 절차

Compound 1f (110 mg, 0.2 mmol) was dissolved in acetonitrile (5 mL) and diisopropylethyl amine (52 mg, 0.4 mmol) was added, followed by the addition of 4-bromobutyronitrile (90 mg, 0.6 mmol). The reaction mixture was refluxed for 16 hours. Volatiles were evaporated and the residue was purified by flash chromatography (silica, 5% MeOH/CH2Cl2) to give compound 3a (115 mg, 94%). MS (CI) m/z 613.3 (MH+).
