Versuchsvorschrift

2-Amino-7,8-dihydro-6H-5-oxa-9-aza-benzocycloheptene-9-carboxylic acid ethyl ester (102 mg, 0.433 mmol) and 2-(2,5-dichloro-pyrimidin-4-ylamino)-3-fluoro-N-methyl-benzamide (150 mg, 0.476 mmol) were placed in isopropyl alcohol (3.00 mL, 39.2 mmol) and 10-camphorsulfonic acid (10.0 mg, 0.0433 mmol) was added. The reaction was microwaved on 300 watts, 120° C. for 20 minutes and then concentrated under reduced pressure. The residue was taken up in DCM (20 mL) and washed with sat. NaHCO3 (20 mL). The organic layer was dried over sodium sulfate, filtered, and concentrated under reduced pressure. Purification by silica gel chromatography using a gradient of 0-100% EtOAc/hex as the eluting solvent to obtain 2-[5-Chloro-4-(2-fluoro-6-methylcarbamoyl-phenylamino)-pyrimidin-2-ylamino]-7,8-dihydro-6H-5-oxa-9-aza-benzocycloheptene-9-carboxylic acid ethyl ester as a yellow foam (115 mg, 52%). LCMS (m/e) 515 (M+H); 1H-NMR (d6-DMSO, 400 MHz) δ 9.37 (bs, 1H), 8.56-8.47 (m, 1H), 8.17 (s, 1H), 7.52-7.36 (m, 4H), 7.28-7.17 (m, 1H), 6.79 (d, 1H, J=8.7 Hz), 4.20-3.81 (m, 4H), 3.70-2.42 (m, 1H), 2.73 (d, 3H, J=4.5 Hz), 1.95-1.80 (m, 2H), 1.36-0.98 (m, 3H).
