Procedure

To a solution of tert-butyl [3-(2-{5-amino-2-[(tert-butoxycarbonyl)amino]phenyl}ethyl)phenyl]carbamate (0.4 g, 0.9 mmol) (prepared in Example C52, step C) and 2,4-dichloro-5-methylpyrimidine (0.152 g, 0.936 mmol) in N,N-dimethylformamide (7 mL) was added potassium carbonate (0.662 g, 4.79 mmol). The resultant mixture was stirred overnight at rt overnight. The reaction was quenched with water. EtOAc was added and the layers were separated. The aqueous layer was extracted with EtOAc twice. The combined organic layers were washed with water and then dried (Na2SO4), filtered and concentrated to give the residue, which was purified by silica gel column chromatography to give the desired product (0.25 g, 39%). LCMS for C29H37ClN5O4 (M+H)+: m/z=554.2.
