(R)-(-)-1-Aminoindan → HCID 89825842, compound

Participants

Reaction Steps

0.20 g (1.20 mmol) of 5-fluoro-2-(trifluoromethyl)pyrimidine, 0.225 g (1.69 mmol) of (1R)-2,3-dihydro-1H-inden-1-amine and 0.50 g (2.41 mmol) of dicyclohexylmethylamine in 1.5 ml of 1-methyl-2-pyrrolidone are heated in a closed cuvette in the microwave at 180° C. for 120 minutes (Biotage Initiator, http://www.biotage.com/DynPage.aspx?id=22001). The crude mixture obtained in this manner is applied to silica gel and purified by column chromatography using the mobile phase heptane/ethyl acetate. Concentration gives 0.34 g of N-[(1R)-2,3-dihydro-1H-inden-1-yl]-2-(trifluoromethyl)pyrimidine-5-amine (melting point 123.7° C., yield 96% at a purity of 95%).
