With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.873397-34-3,Tetrahydro-2H-pyran-3-carboxylic acid,as a common compound, the synthetic route is as follows.
873397-34-3, To a solution of tetrahydro-2H-pyran-3-carboxylic acid (44.0 mg, 0.335 mmol) in DCM (10 mL) was added HOBt (68.0 mg, 0.502 mmol), EDCI (96.0 mg, 0.502 mmo and TEA (0.28 ml, 2 mmol). After stirring at room temperature, Compound 70C (300 mg, 0.335 mmol) was added and the mixture was stirred at room temperature for 2 h. The mixture was concentrated to give a residue which was purified by prep-HPLC (Waters 2767/Qda, Column: Waters Xbridge 19* 150mm lOum, Mobile Phase A: H20 (0.1percentNH4OH), B: ACN) to yield Compound 92 (45 mg, 24.3percent yield) as a white solid. NMR CD3OD (400 MHz) delta 8.30 (s, 1H), 7.65 (s, 1H), 4.52-4.49 (m, 1H), 4.08-4.00 (m, 5H), 3.93-3.89 (m, 2H), 3.86-3.80 (m, 2H), 3.53-3.39 (m, 2H), 3.16-3.10 (m, 1H), 2.97-2.92 (m, 1H), 2.66-2.60 (m, 4H), 2.51-2.48 (m, 2H), 2.29-2.22 (m, 3H), 1.94-1.76 (m, 5H), 1.82-1.69 (m, 4H), 1.15-1.03 (m, 2H).
The synthetic route of 873397-34-3 has been constantly updated, and we look forward to future research findings.
