Synthetic Route of 1105039-93-7<\/a>, A common heterocyclic compound, 1105039-93-7, name is 1-(4-Methoxybenzyl)-1H-pyrazole-4-carboxylic acid, molecular formula is C12H12N2O3, its 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.<\/p>\n

According to Scheme 3 Step 1: A solution of 1-(4-methoxybenzyl)-1H-pyrazole-4-carboxylic acid (34.4 mmol, 8.00 g), oxalyl chloride (68.9 mmol, 5.92 mL) and a drop of DMF in DCM (80 mL) was stirred for 1 hour at room temperature. After evaporation, the crude product was dissolved in DCM (30 mL) and was added at 0 C. to a solution of N,O-dimethylhydroxylamine hydrochloride (103 mmol, 6.31 g) in DCM (100 mL) followed by Et3N (138 mmol, 19.2 mL). The reaction mixture was stirred for 1 hour at room temperature. The reaction was quenched with a saturated solution of Na2CO3 (300 mL) and the aqueous phase was extracted with DCM. The organic phase was dried over MgSO4, was filtered and was concentrated to yield N-methoxy-1-(4-methoxybenzyl)-N-methyl-1H-pyrazole-4-carboxamide (33.8 mmol, 9.30 g, 98%) as a beige solid.LC (Zorbax SB-C18, 3.5 mum, 4.6\u00d750 mm Column): RT=1.78 min; MS m\/z ES+=276.<\/p>\n

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.<\/p>\n
