1240390-36-6, tert-Butyl ((3R,4R)-4-aminotetrahydro-2H-pyran-3-yl)carbamate is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Step 2 {(3R,4R)-4-[7-(1-Methyl-1H-pyrazol-4-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 (1-methyl-1H-pyrazol-4-yl)-amide (0.137 g, 0.349 mmol) and tert-butyl (3R,4R)-4-aminotetrahydro-2H-pyran-3-ylcarbamate (0.111 g, 0.513 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% MeOH in dichloromethane) to give {(3R,4R)-4-[7-(1-methyl-1H-pyrazol-4-ylcarbamoyl)-thieno[3,2-d]pyrimidin-2-ylamino]-tetrahydro-pyran-3-yl}-carbamic acid tert-butyl ester (0.116 g, 0.244 mmol, 52.6%) as a yellow solid. LCMS m/z [M+H]=474, 1240390-36-6
The synthetic route of 1240390-36-6 has been constantly updated, and we look forward to future research findings.
