To a slurry of SI-I (769 g, 1.50 mol) as the tartrate salt (e.e. 98.3%) in dichloromethane (2 L) was added dropwise an aqueous solution of sodium hydroxide (5 N, 126 g, 3.15 mol) at 10 C, all in a round bottom flask (5 L). The reaction mixture was stirred until the pH was 11. The organic layer was separated and the aqueous layer was extracted with dichloromethane twice (500 ml 2). The combined organic layer was washed with water to neutrality, dried over sodium sulfate and filtered. The filtrate was concentrated under reduced pressure to give the SI-II (531 g, 97.5%, HPLC 98.2%) as a light yellow oil.

In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to navigate research efforts intended to implement such knowledge in the development of new catalytic chemistries. Read on for other articles about 239463-85-5.
