Reaction Steps

To a solution of 2,4-dichloro-5-(pyridin-4-yl)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine (1 equiv) in 1,4-dioxane (0.4 M) in a sealable vessel was added tetrahydro-2H-pyran-4-amine hydrochloride (1.5 equiv) and triethylamine (3 equiv). The resulting mixture was heated at 120° C. for 2 h under nitrogen atmosphere. After the reaction was complete, the reaction mixture was cooled to room temperature and concentrated. The residue was purified by silica gel chromatography (0-30% ethyl acetate in petroleum ether) to afford the desired product (34% yield) as a yellow solid. MS (ESI) m/z 460.2 [M+1]+.
