Vorschrift

A solution of 50 mg (100 μmol) N-cyclopropyl-4-{6-[4-(cyclopropylsulfanyl)phenyl]-8-(isobutylamino)imidazo[1,2-a]pyrazin-3-yl}benzamide in 5.0 mL dichloromethane was cooled to −30° C. and 1.16 mL of a 0.15 molar dioxirane solution in acetone were added. After 15 minutes of stirring the mixture was warmed to 23° C., the solvent removed and the residue was purified by chromatography to give 33.3 mg (59%) of the title compound. 1H-NMR (CDCl3): δ=0.67 (2H), 0.86-1.05 (5H), 1.06 (3H), 1.07 (3H), 1.25 (1H), 2.09 (1H), 2.28 (1H), 2.95 (1H), 3.56 (2H), 6.36 (1H), 6.54 (1H), 7.60 (1H), 7.63 (2H), 7.70 (2H), 7.94 (2H), 7.96 (1H), 8.02 (2H) ppm.
