0.25 g (1.09 mmol) of 4-amino-2-chloro-6-ethylpyrimidine-5-carbonitrile, 0.19 g (1.31 mmol) of (1R)-1,2,3,4-tetrahydronaphthalen-1-amine and 0.45 g (3.28 mmol) of potassium carbonate in 2 ml of N,N-dimethylacetamide are heated at 140° C. in a closed cell in a microwave for 30 minutes. The crude mixture obtained in this way is absorbed on silica gel and purified by means of column chromatography using heptane/ethyl acetate as eluent. Following concentration by evaporation, 0.28 g of 4-amino-2-[(1R)-2,3-dihydro-1H-inden-1-ylamino]-6-ethylpyrimidine-5-carbonitrile is obtained (yield 82% at 95% purity).
