Procedure

Cs2CO3 (375 mg, 1 mmol) was added to a solution of 1-[4-(6-methoxy-pyridine-2-yl)-phenyl]-2,2,2-trifluoro-ethanol (67 mg, 0.2 mmol) in 10 ml of anhydrous 1,4-dioxane. The mixture was stirred for 5 min, then was added (S)-3-[4-(2-amino-6-chloro-pyrimidin-4-yl)-phenyl]-2-tert-butoxycarbonylamino-propionic acid (78 mg, 0.2 mmol), and the mixture was heated at 110° C. overnight. After cooling, 5 ml water was added and ethyl acetate (20 ml) was used to extract the product. The organic layer was dried over sodium sulfate. The solvent was removed by rotovap to give 112 mg (S)-3-[4-(2-Amino-6-{2,2,2-trifluoro-1-[4-(6-methoxy-pyridin-2-yl)-phenyl]-ethoxy}-pyrimidin-4-yl)-phenyl]-2-tert-butoxycarbonylamino-propionic acid (yield: 88%).
