5,6,7,8-Tetrahydro-N-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)pyrido[4,3-d]pyrimidin-4-amine (110 mg, 0.39 mmol) was dissolved in anhydrous THF (2 mL). To the mixture was added m-tolylboronic acid (105 mg, 0.78 mmol), Cu(OAc)2 (141 mg, 0.78 mmol) and triethylamine (0.68 g, 0.095 mL) and 390 mg of crushed, activated 4 A molecular seives. The mixture was agitated for 6 h and the solvent was removed under vacuum. The residue was purified using a gradient of ethyl acetate:hexane (0-100%) to give the desired compound as reddish powder (14 mg, 9.6%).
