144689-93-0, name is Ethyl 4-(1-hydroxy-1-methylethyl)-2-propylimidazole-5-carboxylate, belongs to imidazoles-derivatives compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Formula: C12H20N2O3
70(a) Ethyl 1-(2′-cyanobiphenyl-4-yl)methyl-4-(1-hydroxy-1-methylethyl)-2-propylimidazole-5-carboxylate Following a procedure similar to that as described in Example 68(a), but using 4.01 g of ethyl 4-(1-hydroxy-1-methylethyl)-2-propylimidazole-5-carboxylate (prepared as described in Preparation 9), 5.0 g of 4′-bromomethylbiphenyl-2-carbonitrile and 1.97 g of potassium t-butoxide, 6.86 g of the title compound were obtained as crystals, melting at 92-93 C. Nuclear Magnetic Resonance Spectrum (CDCl3) delta ppm: 0.97 (3H, triplet, J=7.5 Hz); 1.16 (3H, triplet, J=7 Hz); 1.65 (6H, singlet); 1.74 (2H, sextet, J=7.5 Hz); 2.67 (2H, triplet, J=7.5 Hz); 4.24 (2H, quartet, J=7 Hz); 5.52 (2H, singlet); 5.77 (1H, singlet); 7.05 (2H, doublet, J=8.5 Hz); 7.42-7.67 (5H, multiplet); 7.76 (1H, doublet, J=8 Hz).
The synthetic route of 144689-93-0 has been constantly updated, and we look forward to future research findings.
