Reaction Steps
A microwave vial is charged with ((3aR,4R,6R,6aS)-2,2-dimethyl-6-{[2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrazolo[1,5-a]pyrimidin-7-yl]amino}tetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl)methanol (0.25 g, 0.58 mmol), 1-chloro-4-iodo-naphthalene (0.38 g, 1.30 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II), complex with dichloromethane (1:1) (29 mg, 0.036 mmol), cesium carbonate (0.70 g, 2.2 mmol) 1,4-dioxane (4.0 mL, 50 mmol) and water (0.60 mL, 30 mmol). The reaction mixture is heated in the microwave at 110° C. for 30 minutes and then cooled to room temperature. The reaction mixture is diluted with ethyl acetate and was washed successively with water, saturated sodium bicarbonate solution and brine. The organic layer is dried over sodium sulfate, filtered and concentrated in vacuo. The crude material is purified by column chromatography (0-80% ethyl actate/hexanes) to provide (s.e.)-[(3aR,4R,6R,6aS)-6-{[2-(4-chloro-1-naphthyl)pyrazolo[1,5-a]pyrimidin-7-yl]amino}-2,2-dimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl]methanol (0.450 g, yield 167%). LCMS: (AA) M+1 465.
