Versuchsvorschrift

To a solution of 4-(5-isopropoxy-6-nitro-1-oxo-1,3-dihydro-isoindol-2-yl)-piperidine-1-carboxylic acid tert-butyl ester from the previous step (850 mg, 2 mmol) in methanol, is added Pd/C (10% on carbon, 100 mg). The mixture is hydrogenated under 1 atm of hydrogen gas. After 4 hours, the mixture is filtered and concentrated. The obtained aniline, as yellow solid, is used for next step without additional purification. To a mixture of the crude product (2 mmol) from previous step, (2,5-dichloro-pyrimidin-4-yl)-[2-(propane-2-sulfonyl)-phenyl]-amine (Intermediate 2, 770 mg, 2.2 mmol), cesium carbonate (1.3 g, 4 mmol), and xantphos (115 mg, 0.2 mmol) in THF (20 mL), is added palladium acetate (22 mg, 5% mmol) in a microwave tube. The mixture is purged with N2 for 3 min. The sealed tube is heated at 150° C. for 20 min under microwave irradiation. The mixture is cooled, filtered and concentrated. The residue is purified by silica gel flash column chromatography (eluent: 65% ethyl acetate in hexanes) to afford a yellow solid. The solid is treated with DCM/TFA (1/1, 10 mL) for 1 hour followed by concentration under vacuum. Final purification using preparative RP LC-MS affords 6-{5-Chloro-4-[2-(propane-2-sulfonyl)-phenylamino]-pyrimidin-2-ylamino}-5-isopropoxy-2-piperidin-4-yl-2,3-dihydro-isoindol-1-one (178) as a white solid. 1H NMR (400 MHz, CDCl3) δ 10.38 (s, 1H), 10.13 (s, 1H), 9.60-9.50 (br, 1H), 9.34-9.21 (br, 1H), 8.46 (d, 1H), 8.26 (s, 1H), 8.08 (s, 1H), 7.91 (dd, 1H), 7.71 (m, 1H), 7.34 (t, 1H), 7.03 (s, 1H), 4.30 (m, 1H), 4.53 (m, 1H), 4.33 (s, 2H), 3.62 (m, 2H), 3.21-3.09 (m, 3H), 2.31-2.21 (m, 2H), 2.09-2.05 (m, 2H), 1.41 (d, 6H), 2.30 (d, 6H); ESMS m/z 599.2 (M+H+).
