Reaction Steps

2,4-Dichloro-5-iodo-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine (1 equiv), 3-hydroxycyclobutanecarbonitrile (1.1 equiv), sodium 2-methylpropan-2-olate (1.2 equiv) and 1,4-dioxane (0.14 M) were combined in a sealable vessel with a stir bar. The resulting mixture was put under nitrogen atmosphere, sealed, stirred vigorously, and heated at 70° C. for 16 h. After cooling to room temperature, the reaction mixture was purified using silica gel chromatography (0 to 50% ethyl acetate in hexane) to give the title compound (77% yield). MS (ESI) m/z 505.0 [M+H]+.
