Resolution of (R:S)-1 -phenyl- 1,2,3,4-tetrahydroisoquinoline (100 g) was carried out using (D)-(-)-tartaric acid in water as per the literature method known in the art (Ref 1.- J. Chem. Soc. Perkin. Trans I, (4), 869-73 (1988), Ref. 2.- Monatshefte Fur. Chemie, vol. 53-54:956-962(1929)) and diastereomeric (D)-(-)-tartaric acid salt of (1S)- 1 -phenyl- 1,2,3,4-tetrahydroisoquinoline was filtered out as a solid. The filtrate containing enantiomerically enriched (D)-(-)-tartaric acid salt of (lR)-l-phenyl-l,2,3,4- tetrahydroisoquinoline was collected and a clear aqueous solution 40 % aq. sodium hydroxide (NaOH, 85 mL) was added at room temperature when solid was precipitated. The precipitated solid was filtered and washed with water and dried. The weight of enantiomerically enriched (lR)-l-phenyl-l,2,3,4-tetrahydroisoquinoline was 61.0 g. (% Purity by HPLC-97.0 %; % Chiral purity of R-isomer -79.0 %).
The synthetic route of 22990-19-8 has been constantly updated, and we look forward to future research findings.
