Electric Literature of 115652-52-3, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 115652-52-3, name is (1-Aminocyclopropyl)methanol hydrochloride. A new synthetic method of this compound is introduced below.
Intermediate: 5-((5-((3′-(3-bromopropoxy)-2′-chloro-2-methyl-[1,1′-biphenyl]-3-yl)methoxy)-4-chloro-2-(((1-(hydroxymethyl)cyclopropyl)amino)methyl)phenoxy)methyl)nicotinonitrile To a solution of 5-((5-((3′-(3-bromopropoxy)-2′-chloro-2-methyl-[1,1′-biphenyl]-3-yl)methoxy)-4-chloro-2-formylphenoxy)methyl)nicotinonitrile (20 mg, 0.031 mmol) in a mixture of 1,2-dichloroethanel (0.8 mL) and EtOH (0.5 mL) was added (1-aminocyclopropyl)methanol, HCl (12 mg, 0.097 mmol), acetic acid (3 muL, 0.052 mmol), and 4 A mol sieves. The reaction was flushed briefly with N2, capped, stirred at room temp for 90 min, then treated dropwise (over 1 h) with sodium cyanoborohydride, 1.0M in THF (65 muL, 0.065 mmol) and stirred at room temp for 18 h. Additional sodium cyanoborohydride (15 mulit) was added dropwise and the reaction was stirred at room temp for 1 h. N,N-diisopropylethylamine (15 muL) was added and the reaction stirred at room temp for 1.5 h. The solvent was removed under a gentle stream of N2 to give the title compound that was used “as is” without purification in subsequent reactions. LC/MS Condition A: ret time 1.18 min; m/e=710(M+H)+.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,115652-52-3, (1-Aminocyclopropyl)methanol hydrochloride, and friends who are interested can also refer to it.
