実験手順

Under an argon atmosphere, 29.0 g (128 mmol) of 4-chloro-6-ethoxycarbonyl-7H-pyrrolo[2,3-d]pyrimidine and 18.0 ml (171 mmol) of 3-chloro-aniline in 430 ml of n-butanol are stirred at 100° C. for 3 hours (almost dissolved after ≈1 hour, then a thick suspension forms). The reaction mixture is cooled to ~50° C., then 400 ml of isopropanol/hexane (1:1) are added thereto. The reaction mixture is then cooled to RT and the product is filtered off and washed with isopropanol and hexane. Stirring from diethyl ether yields the title compound: 1H-NMR (DMSO-d6) 13.0 and 10.53 (2 sb, 2HN), 8.48 (s, 1H), 8.13 (m, 1H), 7.78 (dm, J=8, 1H), 7.76 (s, 1H), 7.45 (t, J=8, 1H), 7.21 (dm, J=8, 1H), 4.37 (q, J=7, 2H), 1.37 (t, J=7, 3H).
