With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.280774-03-0,(1-Isopropylpiperidin-4-yl)methanol,as a common compound, the synthetic route is as follows.
Step D: Preparation of (4-Chlorophenyl)-[2-(1-isopropyl-piperidin-4-ylmethoxy)-3-methyl-3H-imidazol-4-yl]-methanone. (1-Isopropyl-piperidin-4-yl)-methanol (0.08 g) in THF (10 mL) was treated with NaH (60% in mineral oil, 0.02 g). After 30 min, the reaction mixture was cooled to 0 C. and the product of Example V, Step C (0.125 g) in THF (5 mL) was added. After stirring overnight, the reaction mixture was partitioned between brine and EtOAc. The organic portion was separated, washed twice with brine, dried over Na2SO4, filtered and concentrated. The residue was purified by column chromatography with silica gel using a gradient elution of 1-4% MeOH in CH2Cl2 to provide (4-Chloro-phenyl)-[2-(1-isopropyl-piperidin-4-ylmethoxy)-3-methyl-3H-imidazol-4-yl]-methanone (0.07, 51 %) as a white solid. M calc=375; M+H found=376. 1H NMR (400 MHz, CDCl3): delta7.66 (d, J=8.3 Hz, 2H), 7.37 (d, J=8.6 Hz, 2H), 7.13 (s, 1H), 4.24 (d, J=6.1Hz, 2H), 3.69 (s, 3H), 2.88 (br d, J=11.0 Hz, 2H), 2.69 (m, 1H), 2.12 (br dd, J=12.6, 9.6 Hz, 2H), 1.88-1.69 (br m, 1H), 1.37 (br dd (J=23.2, 9.3 Hz, 2H), 0.99 (d, J=6.6 Hz, 6H), 280774-03-0
280774-03-0 (1-Isopropylpiperidin-4-yl)methanol 11147855, apiperidines compound, is more and more widely used in various fields.
