Paragraph 0197, (2019/05/24)
The present disclosure provides a reaction of a chlorine-containing compound using a flow reactor which is less restricted by a solvent to be used. In the present disclosure, an organic compound is produced by supplying a reaction substrate having at least one functional group which can react with chlorine and is selected from the group consisting of hydroxy group, a thiol group, an amino group, a carboxyl group, a thiocarboxyl group, and an acid amide group, and a chlorine-containing compound to a flow reactor together with a trialkyl amine having 9 to 40 carbon atoms and an organic solvent, and allowing the reaction substrate and the chlorine-containing compound to react with each other.

Page/Page column 11, (2011/08/04)
A process for the preparation of solifenacin wherein all the reaction steps, starting from (i) release of (S) -I -phenyl- 1, 2,3, 4 - tetrahydroisoquinoline from its diastereoisomeric salt with D- (-) - tartaric acid, (ii) conversion of (S) - 1 -phenyl - 1, 2, 3, 4 - tetrahydroisoquinoline into 1 - (5) -phenyl - 1, 2, 3, 4 - tetrahydroisoquinolinecarbonyl chloride in the reaction with triphosgene in the presence of pyridine to (iii) the reaction between 1- (5) -phenyl - 1, 2, 3, 4 - tetrahydroisoquinolinecarbonyl chloride and 3- (S) - quinuclidinol in the presence of sodium hydride are carried out without the isolation of intermediates in solid form and the solvents used for the reactions are aprotic solvent. Resulting solifenacin in the free base form is converted into the corresponding succinic acid salt using methods known in the art.
