Procedure

The title compound was prepared according to the procedure described in Tetrahedron 2001, 51, 7027-7034. Pd(OAc)2 (47 mg, 0.21 mmol), and rac-BINAP (131 mg, 0.21 mmol) were stirred in toluene (12 mL) at RT for 12 minutes. This mixture was added to 4-(2-chloro-pyridin-3-yl)-pyrimidine (1.01 g, 5.24 mmol), (3-amino-4-methyl-phenyl)-carbamic acid tert-butyl ester (1.63 g, 7.34 mmol), and K2CO3 (14.5 g, 105 mmol) in toluene (40 mL). The mixture was heated overnight at 130° C. in a sealed tube. The cooled reaction was filtered through a pad of Celite, partially concentrated and the resulting solid was filtered to yield [4-methyl-3-(3-pyrimidin-4-yl-pyridin-2-ylamino)-phenyl]-carbamic acid tert-butyl ester.
