Some common heterocyclic compound, 825-70-7, name is 5-Fluoro-2-methylindoline, molecular formula is C9H10FN, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. COA of Formula: C9H10FN
Under argon atmosphere conditions, add 0.0151g (0.10mmol) of 5-fluoro-2-methylindolinoline (1d), 0.0013g (0.002mmol) of acid eosinY, 0.150g of Antarctic lipase CAL- A, 0.0146 g (0.10 mmol) of n-octyl mercaptan, 0.104 g (0.50 mmol) of allyl-3-methoxyphenyl carbonate (2b), methyl tert-butyl ether (TBME) 2.0 mL;The reaction was stirred at 45 C for 6 hours under a 6w white light. After the reaction, the insoluble enzyme was removed by suction filtration, the solvent was distilled off under reduced pressure, and the solvent was separated by column chromatography. The eluent: (V) petroleum ether / (V) Ethyl acetate = 30/1. 0.0190 g of a yellow liquid product (3db) was obtained with a product yield of 81%.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 825-70-7, its application will become more common.
