Step 2 {(3R,4R)-4-[7-(5,6-Dimethyl-pyridin-2-ylcarbamoyl)-thieno[3,2-d]pyrimidin-2-ylamino]-tetrahydro-pyran-3-yl}-carbamic acid tert-butyl ester To a solution of 2-chloro-thieno[3,2-d]pyrimidine-7-carboxylic acid (5,6-dimethyl-pyridin-2-yl)-amide (0.149 g, 0.466 mmol) and tert-butyl (3R,4R)-4-aminotetrahydro-2H-pyran-3-ylcarbamate (0.121 g, 0.559 mmol) in dioxane (4 mL) was added diisopropylethylamine (0.244 mL, 1.4 mmol). The reaction mixture was heated at 120 C. overnight. The reaction mixture was cooled and then diluted with dichloromethane, washed with aqueous sodium carbonate, then brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The residue obtained was then purified by chromatography (silica, 40 g, 0 to 15% EtOAc in hexanes) to give {(3R,4R)-4-[7-(5,6-dimethyl-pyridin-2-ylcarbamoyl)-thieno[3,2-d]pyrimidin-2-ylamino]-tetrahydro-pyran-3-yl}-carbamic acid tert-butyl ester (0.105 g, 0.210 mmol, 45%) as a yellow solid. LCMS m/z [M+H]=499.
1240390-36-6, 1240390-36-6 tert-Butyl ((3R,4R)-4-aminotetrahydro-2H-pyran-3-yl)carbamate 68077633, aTetrahydropyrans compound, is more and more widely used in various fields.
