Analyzing the synthesis route of 101691-94-5

101691-94-5, As the paragraph descriping shows that 101691-94-5 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.101691-94-5,4-(Iodomethyl)tetrahydro-2H-pyran,as a common compound, the synthetic route is as follows.

To a stirring suspension of methyl 6-cyclopropyl-2-oxo-1,2-dihydropyridine-4-carboxylate (212 mg, 1.1 mmol) in acetonitrile (5 mL) were added potassium carbonate (455 mg, 3.29 mmol) and 4-(iodomethyl)tetrahydro-2H-pyran (CAS-RN 101691-94-5; 744 mg, 3.29 mmol). The reactionmixture was heated at 80C for 16 h and then evaporated in vacuo. The residue was purified by chromatography (silica gel; heptane-ethyl acetate gradient) to produce the title compound (188 mg, 59%). Colourless oil, MS: 292.2 (M+H).
