Vorschrift

50 mg (83.4 μmol) of {4-[8,8-dimethyl-2-(8-oxa-3-azabicyclo[3.2.1]oct-3-yl)-5-oxo-6-(tetrahydropyran-4-yl)-5,6,7,8-tetrahydro-9-oxa-1,3,6-triazabenzocyclohepten-4-yl]phenyl}carbamic acid phenyl ester are placed in a microwave reactor and 25 mg (26 μmol) of 1-methyl-1H-pyrazol-3-ylamine are added. 1 ml of DMF and 2 ml of THF are added. The reactor is heated in a Biotage microwave machine for 30 minutes at 100° C. 100 mg (100 μmol) of 1-methyl-1H-pyrazol-3-ylamine are added and the mixture is heated for 2 hours at 110° C. The solvents are evaporated off. The residue is chromatographed on silica gel, eluting with an MeOH/DCM mixture from (0/100 v/v) up to (5/95 v/v) to give a solid, which is then washed with water and dried. 23 mg of 1-{4-[8,8-dimethyl-2-(8-oxa-3-azabicyclo[3.2.1]oct-3-yl)-5-oxo-6-(tetrahydropyran-4-yl)-5,6,7,8-tetrahydro-9-oxa-1,3,6-triazabenzocyclohepten-4-yl]phenyl}-3-(1-methyl-1H-pyrazol-3-yl)urea are recovered.
