New Advances in Chemical Research, May 2021. The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. Product Details of 118864-75-8, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 118864-75-8, name is (S)-1-Phenyl-1,2,3,4-tetrahydroisoquinoline. In an article，Which mentioned a new discovery about 118864-75-8
The invention relates to a method for preparing a solifenacin succinate ((3R)-1-azabicyclo [2.2.2] octane-3-yl (1S)-1-phenyl-3,4-dihydroisoquinoline-2-(1H)-carboxylate succinate). The method comprises the following steps: 1) preparing a compound (S)-1-phenyl-1,2,3,4-tetrahydroisoquinoline carboxylic acid ethyl ester of formula III from a compound (S)-1-phenyl-1,2,3,4-tetrahydroisoquinoline, serving as a raw material, of formula IV; 2) synthesizing a compound (3R)-1-azabicyclo [2.2.2] octane-3-yl (1S)-1-phenyl-3,4-dihydroisoquinoline-2-(1H)-carboxylate of formula II in an ionic liquid by using the compound (S)-1-phenyl-1,2,3,4-tetrahydroisoquinoline carboxylic acid ethyl ester of formula III; and 3) salifying the compound (3R)-1-azabicyclo [2.2.2] octane-3-yl (1S)-1-phenyl-3,4-dihydroisoquinoline-2-(1H)-carboxylate of formula II in an organic solvent to obtain the compound solifenacin succinate ((3R)-1-azabicyclo [2.2.2] octane-3-yl (1S)-1-phenyl-3,4-dihydroisoquinoline-2-(1H)-carboxylate succinate) of formula I. The preparation method has the advantages that the process is simple, the method is suitable for industrialized production, the yield of the product is high and the purity of the product is high.
