Using analogous reagents and reaction conditions as described in Example 11 above, 1-(4-cyclopropylpyridin-3-yl)imidazolidin-2-one (I-1d: 100 mg, 0.492 mmol) was reacted with 4-chloro-2-methylpyrimidine (68 mg, 0.541 mmol), 2-dicyclohexyl-phosphino-2′,4′,6′-triisopropylbiphenyl (23 mg, 0.0492 mmol), Pd2(dba)3 (23 mg, 0.024 mmol), cesium carbonate (400 mg, 1.23 mmol) and toluene (5 mL) in seal tube at 110° C. for 14 hours. Purification by column chromatography on silica gel (1.5% methanol in chloroform) afforded 76 mg of the product (52% yield).
