With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.62058-03-1, name is trans-4-Aminoadamantan-1-ol, molecular formula is C10H17NO, molecular weight is 167.25, as common compound, the synthetic route is as follows.Application In Synthesis of trans-4-Aminoadamantan-1-ol
General procedure: To a solution of ethyl 1-phenyl-5-(2-methyl-4-oxobutan-2-yl)-1H-pyrazole-4-carboxylate 14b (45 mg, 0.15 mmol) in CHCl3 (9 mL) was added trans-5-hydroxy-2-adamantylamine (25 mg, 0.15 mmol), acetic acid (0.025 mL, 0.45 mmol) and sodium triacetoxyborohydride (85 mg, 0.45 mmol) at room temperature. After stirring at ambient temperature for 16 hours, the reaction mixture was quenched with aq. NaHCO3, extracted with CHCl3, and washed with aq. NaCl. The combined organic layer was dried over Na2SO4 and concentrated in vacuo. The residue was dissolved in methanol (0.30 mL), and added 1.0 N NaOH (0.22 mL, 0.22 mmol) at room temperature. After stirring at ambient temperature for 16 hours, the solvent was removed under vacuum. The mixture of the residue in CHCl3 (1.5 mL) and DIPEA (0.078 mL, 0.45 mmol) and HBTU (35 mg, 0.15 mmol) was stirred at room temperature. After 16 hours, the reaction mixture was quenched with aq. NaHCO3, extracted with CHCl3, and washed with aq. NaCl., then purified with column chromatography (silica gel, eluting with CHCl3/methanol) to give the title compound as a white solid (0.025 g, 42 percent yield).
