Reaction Steps

After tert-butyl 4-{2-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-(trifluoromethyl)phenoxy]ethyl}piperidine-1-carboxylate (266 mg), Na2CO3 (169 mg), and tetrakis(triphenylphosphine)palladium (0) (31 mg) were added to a mixture of 2,4-dichloro-7H-pyrrolo[2,3-d]pyrimidine (100 mg), dioxane (1.6 mL), and water (0.6 mL), the mixture was stirred at 150° C. for 2 hours under microwave irradiation, and cooled to room temperature. After water and EtOAc were added to the reaction mixture, the mixture was stirred, filtered, and washed with EtOAc, whereby tert-butyl 4-{2-[4-(2-chloro-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-2-(trifluoromethyl)phenoxy]ethyl}piperidine-1-carboxylate (121 mg) was obtained as a brown solid.
