Reaction Steps

Palladium acetate (9 mg, 10 mol %), S-Phos (33 mg, 20 mol %), potassium phosphate (340 mg, 4 equivalents) and 3-aminophenylboronic acid hydrate (189 mg, 3 equivalents) were weighed in a two-neck flask equipped with Dimroth condenser, and heated with a drier under reduced pressure, followed by several repetitive argon substitution. A dimethylformamide solution (4 ml) of 4-chloro-2-morpholin-4-yl-7-pyridin-4-yl-6,7-dihydro-5H-pyrrolo[2,3-d]pyrimidine was added with a syringe, followed by stirring at 110° C. for 10 hours. The reaction mixture was added to water, followed by extraction twice with ethyl acetate, and the organic layer was washed with brine, and subsequently dried over sodium sulfate. The drying agent was filtered off, followed by concentration under reduced pressure, and the resulting residue was purified by silica gel column chromatography (dichloromethane/ammonia-methanol), to obtain the desired compound (yellow powder, 62 mg, 41%) was obtained.
