http://muchong.com/html/201208/4876393.html SpletWe have developed a strategy for Pd(dppf)Cl 2-catalyzed quina- zolin-4(3H)-one formation from o-nitrobenzamides and alco- hols via the hydrogen-transfer. Functional groups such as halogen, methoxy, methyl and hydroxyl groups were all well tolerated under the optimized reaction conditions.
