Versuchsvorschrift

To a solution of 3-(indan-5-ylamino)-propionic acid ethyl ester (5 g, 21.4 mmol) and ethyl 4-chloro-2-methylthio-5-pyrimidinecarboxylate (5 g, 21.4 mmol) in 40 mL of n-butanol was added triethylamine (3 mL, 21.4 mmol). The solution was stirred at rt for 2 days. The solvent was removed under vacuum. The residue was extracted into EtOAc, washed with water, brine and then dried with Na2SO4. Removal of the solvent and chromatography on silica, eluting with EtOAc/hexanes (1:10-1:6, v/v), gave 8.2 g (90%) of the titled compound as a white solid. 1H NMR (300 MHz, CDCl3) δ (ppm): 8.22 (s, 1H), 7.16 (d, J=7.6 Hz, 1H), 6.95 (s, 1H), 6.87 (d, J=7.6 Hz, 1H), 4.35 (t, 2H), 4.06 (q, 2H), 3.55 (q, 2H), 2.82 (m, 4H), 2.69 (t, 2H), 2.58 (s, 3H), 2.06(m, 2H), 1.20 (t, 3H), 1.02 (t, 3H).
