Adding a certain compound to certain chemical reactions, such as: 2380-63-4, 1H-Pyrazolo[3,4-d]pyrimidin-4-amine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, 2380-63-4, blongs to pyrimidines compound. COA of Formula: C5H5N5
Synthesis of tert-butyl 3-(4-amino-lH-pyrazolo[3,4-d]pyrimidin-l-yl)piperidine-1-carboxylate: To a solution of lH-pyrazolo[3,4-J]pyrimidin-4-amine (675 mg, 5 mmol) in DMF (12 mL) was added NaH (60%wt in mineral oil, 240 mg, 6.0 mmol, 1.2 eq) and the mixture was stirred at rt for 0.5 h. The tert-butyl 3-((methylsulfonyl)oxy)piperidine-l-carboxylate (1.67 g, 6 mmol, 1.2 eq) was added and the mixture was heated to 100 C for 16 h. The solution was cooled to rt and the reaction was quenched with brine (50 mL) and extracted with EtOAc (80 mL x 4). The organic layers were dried over Na2S04i concentrated in vacuo to afford a residue which was purified by column chromatography (silica gel, pure EtOAc) to give the title product (700 n yield: 50%) as a light yellow solid. lH NMR (400 MHz, DMSO-d6) delta: 9.24 (br s, IH), 8.72 (br IH), 8.41 (s, IH), 8.33 (s, IH), 4.67-4.62 (m, IH), 4.05-3.58 (m, 3H), 3.40-3.33 (m, IH), 2.9 2.95 (m 1 H), 2.16-2.04 (m, IH), 1.61-1.24 (m, 11H). ESI-MS (M+H+): 319.0.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,2380-63-4, its application will become more common.
