1187173-43-8, 2,7-Diazaspiro[4.5]decan-1-one hydrochloride is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
2,7-Diazaspiro[4.5]decan-1 -one (150 mg, 0.973 mmol) was dissolved in a mixture of triethylamine (0.542 mL, 3.89 mmol) and dichloromethane (10 mL), and 3-chloro-4- [(trifluoromethyl)oxy]benzenesulfonyl chloride (344 mg, 1.167 mmol) was added. After 16 h the reaction mixture was concentrated in vacuo and the resulting residue was purified by silica column chromatography on SP4 (gradient elution: 0 – 20% MeOH – DCM) to give 7-({3-chloro-4-[(trifluoromethyl)oxy]phenyl}sulfonyl)-2,7- diazaspiro[4.5]decan-1 -one (350 mg, 0.839 mmol, 86% yield) as a white solid. 1 H NMR (400 MHz, DMSO-d6) delta ppm 1 .37 – 1.49 (m, 2 H) 1.49 – 1.65 (m, 1 H) 1.65 – 1 .76 (m, 1 H) 1.88 – 2.08 (m, 2 H) 2.27 – 2.40 (m, 2 H) 3.19 (t, J=6.63 Hz, 2 H) 3.36 (d, J=1 1 .51 Hz, 1 H) 3.64 (d, J=1 1 .62 Hz, 1 H) 7.77 (s, 1 H) 7.80 – 7.87 (m, 2 H) 8.06 (dd, J=1.59, 0.82 Hz, 1 H). MS ES+ve m/z 413 (M+H)., 1187173-43-8
As the paragraph descriping shows that 1187173-43-8 is playing an increasingly important role.
