5264-35-7, 5-Methoxy-3,4-dihydro-2H-pyrrole is a pyrrolines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,5264-35-7
To a solution of ethyl N-[3-(3-amidinophenyl)-2-(E)-propenyl]-N-[3-methyl-4-(piperidin-4-yloxy)phenyl]sulfamoylacetate (700 mg) obtained in example 65(a) in ethanol (15 ml) were added successively 5-methoxy-3,4-dihydro-2H-pyrrole (405 mg), which was prepared from 2-pyrrolidinone according to the method described in Org. Prep. Proced. Int., 24, 147 (1992), and triethylamine (0.57 ml) at room temperature, and the resulting mixture was stirred at room temperature overnight and then evaporated in vacuo.. The residue obtained was purified by preparative HPLC (YMC-Pack ODS-A; YMC, eluent: 22 percent acetonitrile/water) to afford an amorphous solid (565 mg).. Subsequently, to a solution of the amorphous solid obtained (151 mg) in ethanol (4 ml) was added a 4N solution of hydrogen chloride in dioxane (2 ml), and the resulting mixture was evaporated to dryness in vacuo.. The residue obtained was dissolved in water and then lyophilized to afford the title compound (157 mg, yield: 66 percent) as a colorless amorphous solid. 1H NMR (400MHz, DMSO-d6) delta ppm: 1.23 (3H, t, J=7.0), 1.72-1.85 (2H, m), 1.98-2.14 (4H, m), 2.16 (3H, s), 2.96 (2H, t, J=8.0), 3.46-3.81 (6H, m), 4.20 (2H, q, J=7.0), 4.33 (2H, s), 4.44 (2H, d, J=6.0), 4.73 (1H, m), 6.44 (1H, dt, J=16.0, 6.0), 6.57 (1H, d, J=16.0), 7.07 (1H, d, J=9.0), 7.24 (1H, dd, J=9.0, 2.5), 7.29 (1H, d, J=2.5), 7.55 (1H, t, J=8.0), 7.69 (1H, d, J=8.0), 7.72 (1H, d, J=8.0), 7.89 (1H, s); IR (KBr, cm-1): 1738, 1671, 1350, 1157.
The synthetic route of 5264-35-7 has been constantly updated, and we look forward to future research findings.
