실험 절차

A solution of 2-chloro-3-(quinolin-6-yl)propanal (1.0 g, 2.54 mmol) and 5-bromopyrimidin-2-amine (0.53 g, 3.05 mmol) in 2-methyl-butan-2-ol (10 mL) was stirred at 135° C. for 12 h. After cooling, the solvent was removed in vacuo and the residue was purified by flash chromatography in silica gel eluting with a CH2Cl2/MeOH gradient to afford a mixture of the title compound and 6-(6-bromo-imidazo[1,2-a]pyrimidin-2-ylmethyl)quinoline (250 mg, 29%) as brown solid. LCMS (method E): [MH]+=339/341, tR=3.51 min.
