In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 1467-84-1, name is (trans-4-Aminocyclohexyl)methanol, the common compound, a new synthetic route is introduced below. category: alcohols-buliding-blocks
To a solution of trans-4-aminocyclohexyl)methanol (CXXXIV) (1.0 g, 6.04 mmol) and HATU (2.78 g, 7.30 mmol) in DMF (15 mL) was added DIPEA (4.03 mL, 23.07 mmol) and the mixture was stirred for 10 min. Then, 5-bromo-1-(tetrahydro-2H-pyran-2-yl)-1H-indazole-3-carboxylic acid (LII) (2.5 g, 7.69 mmol) was added and the mixture was stirred at room temperature for 18 h. The LC-MS of mixture showed near completion of the starting material. The solvents were concentrated in vacuo, the residue partitioned between EtOAc and saturated aqueous NaHCO3, organic layer was separated, washed with water and brine. The organic layer was dried over anhydrous Na2SO4, solvents removed in vacuo and the crude product was purified by column chromatography using (90-100% EtOAc/hexanes) to obtain 5-bromo-N-trans-4-(hydroxymethyl)cyclohexyl)-1-(tetrahydro-2H-pyran-2-yl)-1H-indazole-3-carboxamide (CXXXV) as a white solid (2.06 g, 4.72 mmol, 61.4% yield). ESIMS found for C20H26BrN3O3 m/z 438.1 (M+H).
The synthetic route of 1467-84-1 has been constantly updated, and we look forward to future research findings.
