With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.278788-66-2,(R)-tert-Butyl 3-(hydroxymethyl)piperazine-1-carboxylate,as a common compound, the synthetic route is as follows.
Intermediate 78 tert-Butyl (3R)-4-(5-aminothiazolo[5,4-d]pyrimidin-7-yl)-3-(hydroxymethyl)-piperazine-1-carboxylate [0299] To a solution of Intermediate 4 (4.63 mmol) and (R)-3-(hydroxymethyl)-piperazine-1-carboxylic acid tert-butyl ester (1 g, 4.62 mmol) in DMF (20 mL) was added DIPEA (6.94 mmol). The reaction mixture was heated at 100 C. for 7 h, then cooled and stirred at room temperature for 2 days. The reaction mixture was concentrated in vacuo and partitioned between EtOAc and water. The organic layers were dried over sodium sulfate and concentrated again. The resulting orange oil was purified by column chromatography on silica gel, with a gradient of 1% increasing to 20% MeOH in DCM, to yield the title compound (0.42 g, 24.8%) as a yellow gummy solid. LCMS (ES+) 367.8 (M+H)+, RT 0.8 minutes (method 3)., 278788-66-2
The synthetic route of 278788-66-2 has been constantly updated, and we look forward to future research findings.
