Versuchsvorschrift
The title compound was prepared in an analogous manner as 3-(7H-pyrrolo[2,3-d]pyrimidin-4-ylamino)-thiophene-2-carboxylic acid 3-chloro-benzylamide using 5-methyl-3-(7H-pyrrolo[2,3-d]pyrimidin-4-ylamino)-thiophene-2-carboxylic acid methyl ester instead of 3-(7H-pyrrolo[2,3-d]pyrimidin-4-ylamino)-thiophene-2-carboxylic acid methyl ester and obtained in 50% yield (HPLC: 98%, RT: 3.85 min). 1H NMR (DMSO-d6) 11.98 (br s, 1H), 11.39 (s, 1H), 8.68 (t, J=6.0 Hz, 1H), 8.39 (s, 1H), 8.28 (d, J=1.1 Hz, 1H), 7.40-7.28 (m, 5H), 6.41 (dd, J=3.3, 1.8 Hz, 1H), 4.48 (d, J=5.9 Hz, 2H), 2.55 (s, 3H); MS (m/z) 398 [M+H]+ (35Cl).
