Application of 423165-07-5,Some common heterocyclic compound, 423165-07-5, name is exo-3-(3-Isopropyl-5-methyl-4H-1,2,4-triazol-4-yl)-8-azabicyclo[3.2.1]octane, molecular formula is C13H22N4, 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.
Step 7: 1-acetyl-N-(3-chloro-4-methylphenyl)-N-(3-(3-exo-(3-isopropyl-5-methyl-4-hydro-1,2,4-triazol-4-yl)-8-azabicyclo[3.2.1]oct-8-yl)propyl)-4-piperidinylcarboxamide (compound 11) A solution of 1-acetyl-N-(3-chloro-4-methylphenyl)-N-(3-chloropropyl)-4-piperidinylcarboxamide (185 mg, 0.5 mmol), the product prepared in step 6 (129 mg, 0.55 mmol) and triethylamine (0.21 mL, 1.5 mmol) in acetonitrile (5 mL) was stirred and refluxed for 24 hours, and then vaporized off the solvent, diluted with ethyl acetate, and washed with water and saline respectively. The separated organic phase was dried with sodium sulfate and concentrated under reduced pressure. The concentrate was separated through column chromatography (dichloromethane/methanol=20/1 to 10/1, v/v) to give a yellowish foam-like product (28 mg, yield: 10%). 1HNMR (CDCl3, 300 MHz) delta: 7.36-7.30 (m, 1H), 7.20 (s, 1H), 7.01-6.97 (m, 1H), 4.55-4.48 (m, 1H), 4.30-4.20 (m, 1H), 3.49-3.44 (m, 1H), 3.31 (br-s, 2H), 3.00-2.96 (m, 1H), 2.89-2.79 (m, 1H), 2.43 (s, 3H), 2.48-2.35 (m, 6H), 2.05 (s, 3H), 2.18-1.96 (m, 5H), 1.75-1.62 (m, 12H), 1.38-1.25 (m, 6H);
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route exo-3-(3-Isopropyl-5-methyl-4H-1,2,4-triazol-4-yl)-8-azabicyclo[3.2.1]octane, its application will become more common.
