Reaction Steps

1.77 g (5.85 mmol) of 4-chloro-6-ethyl-8,8-dimethyl-2-methylsulfanyl-7,8-dihydro-6H-9-oxa-1,3,6-triazabenzocyclohepten-5-one, 2.27 g (6.73 mmol) of [3-fluoro-4-(4,4,5,5-tetramethyl[1,3,2]dioxaborolan-2-yl)phenyl]carbamic acid tert-butyl ester and 14.63 ml of a 2 M solution of Na2CO3 in 35 ml dioxane are mixed together, followed by degassing 5 times with argon. 339 mg (293 μmol) of tetrakis(triphenylphosphine)palladium (0) are added and the mixture is degassed a further 3 times with argon and then heated at 90° C. for 2 hours 30 minutes. The resulting mixture is allowed to cool. It is poured into water. The product is filtered off, washed with water, dissolved in DCM, dried and concentrated. It is taken up in Et2O, and the mixture is stirred, filtered and dried. 2.94 g of [4-(6-ethyl-8,8-dimethyl-2-methylsulfanyl-5-oxo-5,6,7,8-tetrahydro-9-oxa-1,3,6-triazabenzocyclo hepten-4-yl)-3-fluorophenyl]carbamic acid tert-butyl ester are recovered.
