Related Products of 56441-97-5,Some common heterocyclic compound, 56441-97-5, name is Methyl 4-(benzyloxy)-3-methoxybenzoate, molecular formula is C16H16O4, 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.
34 ml of glacial acetic acid, fuming nitric acid (13.6 mmol, 5.8 ml) was added to a 100 ml round-bottomed flask and stirred at 0 C in an ice bath. Methyl 3-methoxy-4-benzyloxybenzoate 13.3 mmol, 3.7 g) was slowly added to the solution in portions and the reaction was continued at 0 C for 30 minutes and then at room temperature for 6 hours.The reaction solution was slowly poured into 120 ml of ice water, stirred to precipitate solid, filtered, washed with a small amount of ether and dried to give 4.0 g of yellow solid as 2-nitro-4-benzyloxy-5-methoxybenzene acid methyl ester, yield% 94.7
The synthetic route of 56441-97-5 has been constantly updated, and we look forward to future research findings.
