24398-88-7, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 24398-88-7 as follows.

A mixture of 3- bromo-benzoic acid ethyl ester (229 mg, 1 mmol), 4-methylpiperidine ( 120 mg, 1 .2 mmol ), Pd2(dba)3 (25 mg ), BINAP (25 mg), and fBuONa ( 130 mg ) in toluene (6 mL) was heated at 90 C overnight. After the reaction was completed as indicated by TLC, the mixture was filtered and the filtrate was concentrated in vacuo. Ethyl acetate (50 mL) and aq. HC1 ( I , 20 mL) were then added. The aqueous portion was extracted with ethyl acetate (2 x 50 mL). The combined organic layers were washed with brine (50 mL), dried over anhydrous sodium sulfate, and filtered, concentrated, and purified by chromatography to give the title compound (76 mg, 3 1 %).
