Procedure

A mixture of 4-(2-chloro-5-(methylthio)pyrimidin-4-yl)morpholine (0.3 g, 1.22 mmole), 4-aminophenylboronic acid pinacol ester (0.58 g, 2.68 mmole), sodium bicarbonate (0.28 g, 2.68 mmole), Pd(PPh3)4 (0.14 g, 0.122 mmole), dioxane (15 ml) and H2O (3.5 ml) was heated to reflux. After 12 hrs, the reaction mixture was cooled, diluted with EA, washed with brine, and dried (MgSO4), and the solvent was removed in vacuo. Purification on silica gel (EA/Hex=1/2) yielded the desired compound (180 mg, 49%).
