Komponenten

Versuchsvorschrift

Triethylamine (1.4 mL, 10 mmol) was added dropwise to a solution of 2-bromo-1-(3,5-dimethylphenyl)-2-(2-phenylmethyloxy-4-pyridyl)ethanone hydrobromide (4.8 g, 9.8 mmol) and thiourea (0.77 g, 11 mmol) in acetonitrile (40 mL) and the mixture was stirred at room temperature for 3 hours. The solvent was removed under reduced pressure, a saturated aqueous solution of sodium hydrogencarbonate was added to the residue and extracted with ethyl acetate. The organic layer was washed with water, dried and the solvent was distilled off. The resulting crude crystals were recrystallized from ethyl acetate to obtain 2.0 g (5.2 mmol, yield 53%) of the title compound.
