Product Description

Bioactive J-147 is a particularly effective neuroprotective agent with oral activity that can enhance cognitive abilities.

Produce way:

Slowly add trifluoroacetic anhydride (0.33mL, 2.36mmol) dropwise to a stirred solution of 1- (2,4-dimethylphenyl) -2- [(3-methoxyphenyl) methylene] hydrazide (500mg, 1.97mmol) and triethylamine (0.33mL, 2.36mmol) in dichloromethane (5mL) at 0 ℃ under nitrogen protection. The reaction mixture was stirred continuously at 0 ℃ for 1.5 hours. After the reaction was completed, the mixture was concentrated and the residue was purified by column chromatography using acetone/hexane (1:10) as the eluent to obtain the target product 2,2,2-trifluoroacetic acid 1- (2,4-dimethylphenyl) -2- [(3-methoxyphenyl) methylene] hydrazide (71 mg, yield 83%) as a light yellow oil. The 1HNMR (CDCl3) data is as follows: δ7.26-7.23（m，4H），7.19（d，J=8.0Hz，1H），7.12（d，J=7.5Hz，1H），7.03（d，J=8.0Hz，1H），6.92（dd，J=8.5,2.0Hz，1H），3.79（s，3H），2.39（s，3H），2.08（s，3H）。 Analysis results of high-resolution mass spectrometry (ESI-TOF, m/z): The calculated value of C18H18N2O2F3 ([M+H]+) is 351.1320; The measured value is 351.1311.
