Versuchsvorschrift

A solution of 4-chloro-5,6-dimethyl-N-(pyridin-2-ylmethyl)pyrimidin-2-amine (200 mg, 0.8 mmol, Step C) and cyclopentanamine (85 mg, 1 mmol) in acetonitrile (5 mL) was treated with 3.5 M hydrogen chloride in dioxane (0.2 mL), and the resultant mixture was refluxed overnight. The reaction mixture was diluted with water (50 mL), and the resultant precipitate was collected by filtration. The precipitate was purified by crystallization from ethanol (10 mL) to afford 42 mg (19%) of the titled compound as the hydrochloride salt as a white solid. 1H NMR (300 MHz, DMSO-d6) δ ppm 1.40-1.50 (m, 4H), 1.50-1.67 (m, 4H), 1.88 (s, 3H), 2.27 (s, 3H), 4.00-4.12 (m, 1H), 4.92 (d, J=4.57 Hz, 2H), 7.71-4.83 (m, 2H), 7.83 (d, J=8.06 Hz, 1H), 8.17-8.25 (m, 1H), 8.33-8.39 (m, 1H), 8.76 (d, J=5.10 Hz, 1H), 13.24 (bs, 1H); MS (ESI) m/z 398.5 (ESI) (M+1)+.
