Procedure

A mixture of 7-chloro-2,3-dihydroimidazo[1,2-c]pyrimidin-5(1H)-one (300 mg, 1.75 mmol), cyclopropylboronic acid (300 mg, 3.50 mmol), 4,4′-bipyridine (273 mg, 1.75 mmol), copper (I) acetate (214 mg, 1.75 mmol) and Na2CO3 (371 mg, 3.50 mmol) in 1,2-dichloroethane (DCE) (20 mL) was stirred at 70° C. for 3 h and concentrated to remove solvent under vacuo. Purification via Biotage system with inverse phase column (water and acetonitrile as eluent) afforded the title product (200 mg).
