A microwave vial containing a mixture of ethyl 2-(4-chloro-2-(methylthio)pyrimidin-5-yl)-2-methylpropanoate (2.08 g, 7.57 mmol), tert-butyl(trans-3-aminocyclobutyl)carbamate (1.551 g, 8.33 mmol), tris(dibenzylideneacetone) dipalladium (0) (0.520 g, 0.568 mmol), dicyclohexyl(2′,4′,6′-triisopropyl-3,6-dimethoxy-[1,1′-biphenyl]-2-yl)phosphine (0.731 g, 1.363 mmol) and sodium tert-butoxide (2.317 ml, 18.93 mmol) in dioxane (15 mL) was purged with argon and capped. The reaction mixture was heated at 100° C. for 3 hours, cooled, and partitioned between water (200 mL) and ethyl actate (200 mL). The organic was isolated and concentrated under reduced pressure. Purification using the ISCO eluting with 0-70% EtOAc/hexane to give the desired product tert-butyl(trans-3-(5,5-dimethyl-2-(methylthio)-6-oxo-5H-pyrrolo[2,3-d]pyrimidin-7(6H)-yl)cyclobutyl)carbamate (0.9 g, 2.378 mmol, 31.4% yield). m/z: 379.2 (M+1).
