Versuchsvorschrift

The (5,6,7,8-Tetrahydro-pyrido[4,3-d]pyrimidin-4-yl)-(4-trifluoromethylphenyl)amine (100 mg, 0.34 mmol) was dissolved in anhydrous THF (2 mL). To the mixture was added phenylboronic acid (83 mg, 0.68 mmol), Cu(OAc)2 (124 mg, 0.68 mmol) and triethylamine (0.68 g, 0.095 mL). The mixture was agitated for 6 h and the solvent was removed under the vacuum. The residue was purified using a gradient of ethyl acetate:hexane (0-400%) to give the desired compound as reddish powder (8.0 mg, 6.0%).
