A common heterocyclic compound, the Thiomorpholine compound, name is Thiomorpholine 1,1-dioxide,cas is 39093-93-1, mainly used in chemical industry, its synthesis route is as follows.
A mixture of (S) – 4 – (1 – (4-fluoro-phenyl) – 2-methoxy-ethylamine) – 5-methyl-pyrrolo [2,1-f] [1, 2, 4] triazine-6-carboxylic acid (100 mg, 0 . 29mmol) and thiomorpholine -1,1-dioxide (58 mg, 0 . 44mmol) dissolved in N, N-dimethyl formamide (5 ml) in, then add 1-hydroxy benzotriazole (51 mg, 0 . 38mmol), 1-ethyl-3 – (3-dimethylamino-propyl) carbodiimide hydrochloride (74 mg, 0 . 38mmol) and triethylamine (88 mg, 0 . 87mmol), stirring the mixture at room temperature until the TLC reaction monitoring raw material the reaction is complete, to be added in to the reaction solution (100 ml), ethyl acetate (50 ml ¡Á 3) extraction, then by saturated sodium chloride solution (100 ml ¡Á 2) washing, the organic phase is dried with anhydrous sodium sulfate, concentrated under reduced pressure, the resulting residue is purified with silica gel column chromatography, to obtain (S) – (1,1-dioxy thiophosphoro morphline) – {4 – [1 – (4-fluorophenyl) – 2-methoxy-ethylamine] – 5-methyl-pyrrolo [2,1-f] [1, 2, 4] triazin-6-yl}}-methyl ketone (105 mg, white solid), yield: 78.4percent., 39093-93-1
As the rapid development of chemical substances, we look forward to future research findings about 39093-93-1
