Versuchsvorschrift

A mixture of methyl 2,4-dichloro-6-(m-tolylamino)pyrimidine-5-carboxylate (502.6 mg, 1.610 mmol), N-ethyldiisopropylamine (0.3 mL, 1.718 mmol) and N-ethylpiperazine (0.21 mL, 1.653 mmol) in THF (8 mL) was stirred at RT for 12 h. Saturated aq NaHCO3 was added and the resulting mixture was extracted with EtOAc. The organic layers were washed with saturated aq NaHCO3, water, and brine, were dried over anhydrous Na2SO4, and then filtered through SiO2. The filtrate was concentrated under reduced pressure and the residue was purified by column chromatography (SiO2, hexanes/EtOAc=4/1) to give the title compound (152.6 mg, 24%). 1H NMR (500 MHz, CDCl3) δ ppm 1.12 (t, J=6.5 Hz, 3H), 2.35 (s, 3H), 2.48 (br s, 6H), 3.82-3.97 (m, 7H), 6.92-6.93 (m, 1H), 7.21-7.22 (m, 1H), 7.37-7.42 (m, 2H), 10.45 (s, 1H). [M+H] calc'd for C19H25ClN5O2, 390. found, 390.
