Versuchsvorschrift

To a 10-ml microwave vessel was added, 2-chloro-6-[(5-cyclopropyl-1H-pyrazol-3-yl)amino]-5-fluoronicotinonitrile (Method 1, 600 mg, 2.3 mmol), N-[5-(1-aminoethyl)-2-fluorophenyl]methanesulfonamide (Method 61, 500 mg, 2.3 mmol), DIEA (0.5 ml, 2.76 mmol), and n-butanol (5 ml). The vessel was sealed and subjected to microwave heating at 150° C. for 5 hours (CEM Discover System). The resulting mixture was then purified by silica gel chromatography using 5% MeOH/DCM. The racemic product obtained was then chirally purified by HPLC on Chiralcel OJ column (500×50 mm, 20 microns) using 50:25:25:0.1% of hexane/MeOH/EtOH/diethylamine at 118 ml/min. The chiral purification gave 220 mg of N-{5-[(1R)-1-({3-cyano-6-[(5-cyclopropyl-1H-pyrazol-3-yl)amino]-5-fluoropyridin-2-yl}amino)ethyl]-2-fluorophenyl}methanesulfonamide 1H NMR: δ 11.77-12.26 (br s, 1H), 9.51 (s, 1H), 9.34-9.48 (br s, 1H), 7.62 (d, J=10.55 Hz, 1H), 7.39 (d, J=8.29 Hz, 1H), 7.02-7.23 (m, 3H), 6.00 (s, 1H), 5.07-5.24 (m, 1H), 2.95 (s, 3H), 1.81-1.95 (m, 1H), 1.49 (d, J=7.54 Hz, 3H), 0.88-0.97 (m, 2H), 0.57-0.68 (m, 2H). MS: Calcd.: 473. Found: [M+H]+ 474 and 223 mg of N-{5-[(1S)-1-({3-cyano-6-[(5-cyclopropyl-1H-pyrazol-3-yl)amino]-5-fluoropyridin-2-yl}amino)ethyl]-2-fluorophenyl}methanesulfonamidel; 1H NMR: 11.73-12.38 (br s, 1H), 9.42 (s, 1H), 8.41-9.12 (br s, 1H), 7.61 (d, J=11.30 Hz, 1H), 7.37 (d, J=7.54 Hz, 1H), 6.96-7.24 (m, 3H), 6.02 (s, 1H), 5.05-5.26 (m, 1H), 2.90 (s, 3H), 1.79-1.96 (m, 1H), 1.49 (d, J=6.78 Hz, 3H), 0.89-0.98 (m, 2H), 0.59-0.67 (m, 2H). MS: Calcd.: 473. Found: [M+H]+ 474.
