The downstream synthesis method of this compound is introduced below.

A solution of sodium bis(trimethylsilyl)amide (1.12 g, 6.13 mmol) in 16.2 mL of THF was cooled to -78C and a solution of ethyl 4-(2,2-dimethyl-4-oxo-thiochroman-6- ylethynyl)-benzoate (1.86 g, 5.10 mmol) in 15.0 mL was added slowly. After 30 minutes a solution of 2-[N,N-bis(trifluoromethanesulfonyl)amino]-5-pyridine (2.40 g, 6.13 mmol) in 10 mL of THF was added. After 5 minutes the solution was warmed to room temperature and stirred overnight. The reaction was quenched by the addition of saturated aqueous NH4CI and extracted with EtOAc. The combined organic layers were washed with 5% aqueous NaOH and H2O before being dried (MgSO4) and concentrated under reduced pressure. Ethyl 4-((2,2-dimethyl-4-trifluoromethanesulfonyloxy-(2H)- thiochromen-6-y-l)ethynyl)-benzoate, 1.53 g (61%), was isolated by column chromatography (2% EtOAc/hexanes) as a yellow solid. 1H NMR (300 MHz, CDCl3) delta: 8.03 (2H, d, J=8.4 Hz), 7.61 (IH5 d, J=I.8 Hz), 7.59 (2H, d, J=8.4 Hz), 7.41 (IH, dd, J=1.8, 8.1 Hz), 7.29 (IH, d, J=8.1 Hz), 5.91 (IH, s), 4.39 (2H, q, J=7.1 Hz), 1.53 (6H, s), 1.41 (3H, t, J=7. I Hz).

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 145100-50-1, 1,1,1-Trifluoro-N-(pyridin-2-yl)-N-((trifluoromethyl)sulfonyl)methanesulfonamide, other downstream synthetic routes, hurry up and to see.

Here is a downstream synthesis route of the compound, 145100-50-1, blongs to pyridine-derivatives compound. 145100-50-1

General procedure: Either (2S)-13 or (2R)-13 was dissolved in anhydrous DCM, and1.5 equivalents of 2-Pyridyltriflimide were added. The flask was placedunder N2 atmosphere and cooled to -78 C. 3.0 equivalents of N,Ndiisopropylethylaminewere added and the reaction slowly warmed toroom temperature and stirred for 20 h. Saturated aqueous ammoniumchloride was added, and extraction done with DCM. Organic fractionswere dried over sodium sulfate and purification was done by flashchromatography 98:2 (DCM:MeOH). TLC eluents used (95:5Dichloromethane: MeOH).

With the rapid development of chemical substances, we look forward to future research findings about 145100-50-1.
