Application of 1663-61-2,Some common heterocyclic compound, 1663-61-2, name is (Triethoxymethyl)benzene, molecular formula is C13H20O3, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Step-1: To a stirred solution of methyl 2-oxo-2,3-dihydro-1H-pyrrolo[3,2-b]pyridine-6-carboxylate (0.18 g, 0.9366 mmol) in acetic anhydride (4 ml) was added triethyl orthobenzoate (0.630 g, 2.8098 mmol) at RT and the mixture was refluxed for 3 h at 110° C. The reaction mixture was evaporated and the resulting residue was used as such into next step without purification. [0212] Step-2: To a stirred solution of product from step-1 (0.18 g) in DMF (4 ml) was added N-(4-aminophenyl)-N-methyl-2-(4-methylpiperazin-1-yl)acetamide (0.180 g, 0.6861 mmol) at RT and the reaction mixture was heated at 110° C. for 1 h. The reaction mixture was cooled to RT and stirred with triethyl amine (1 ml) for half an hour. The reaction mixture was evaporated and the crude product was purified by column chromatography using 0 to 10percent methanol in dichloromethane as eluent to afford (Z)-methyl 1-acetyl-3-((4-(N-methyl-2-(4-methylpiperazin-1-yl) acetamido)phenylamino)(phenyl)methylene)-2-oxo-2,3-dihydro-1H-pyrrolo[3,2-b]pyridine-6-carboxylate as yellow solid. MS (ES+): m/z 583.4 (MH+).
The synthetic route of 1663-61-2 has been constantly updated, and we look forward to future research findings.
