実験手順

N-BOC-D-phenylalanine (3.3 g), 1-hydroxy-1H-benzotriazole hydrate(1.9 g) and N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimid hydrochloride (2.37 g) were stirred in DMF (30 ml) for 30 minutes Then methyl 3-amino-5-[[5-bromo-4-(prop-2-ynyloxy)pyrimidin-2-yl]amino]benzoate (3.88 g) were added and the mixture stirred over night. Then ethyl acetate (500 ml) was added and the reaction mixture washed subsequently with hydrochloric acid (0.1 n), saturated NaHCO3-solution, water and brine. After drying (Na2SO4) the organic phase was evaporated and the residue subjected to column chromatography (ethyl acetate/dichloromethane) to yield 5.36 g of the title compound.
