Versuchsvorschrift

To a solution of N-{[(1,1-dimethylethyl)oxy]carbonyl}-3-methyl-D-valine (Intermediate 76, 53.9 mg) in dry N,Ndimethylformamide (1 ml), DIPEA (50.9 μl, 0.292 mmol) and then HATU (102 mg, 0.268 mmol) were added and the reaction mixture was stirred for 15 minutes at room temperature under argon. Then 2-[(3,3-dimethyl-2,3-dihydro-1-benzofuran-4-yl)oxy]-5-pyrimidinamine (Intermediate 65, 30 mg) was added and the reaction mixture was stirred at 60° C. under argon during 12 hours. The reaction was quenched with brine (1 ml), diluted with water (2 ml) and extracted with ethyl acetate (2×5 ml). The organic layer was dried over sodium sulphate and evaporated. The residue obtained was purified on silica gel (Companion instrument) with a gradient cyclohexane/ethylacetate 100/0 to 70/30. This afforded the title compound (17 mg).
