Application of 36947-68-9, These common heterocyclic compound, 36947-68-9, name is 2-Isopropyl-1H-imidazole, 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.
Example A29 A mixture of 2-isopropylimidazole (3.0 g, 27.2 mmol) and DIEA (5.28 g, 40.9 mmol) in DCM (75 mL) was treated drop-wise with methoxyethoxymethyl chloride [MEM-Cl](4.24 g, 34.0 mmol) and stirred at RT for 16 h. The mixture was washed with water, then brine, dried over Na2SO4 and concentrated to dryness to afford 2-isopropyl-1-((2-methoxyethoxy)methyl)-1H-imidazole (3.91 g, 72%). 1H NMR (400 MHz, DMSO-d6): delta 7.11 (d, J=1.3 Hz, 1H), 6.74 (d, J=1.3 Hz, 1H), 5.30 (s, 2H), 3.47-3.46 (m, 2H), 3.38-3.37 (m, 2H), 3.19 (s, 3H), 3.08-3.07 (m, 1H), 1.18 (d, J=6.8 Hz, 6H).
Statistics shows that 2-Isopropyl-1H-imidazole is playing an increasingly important role. we look forward to future research findings about 36947-68-9.
