Description
Summary:A number of 1D and 2D NMR techniques, such as <sup>1</sup>H, <sup>13</sup>C, DEPT 135, <sup>1</sup>H-<sup>1</sup>H COSY, HSQC, and HMBC, were utilized for the structure verification of 4-(8-propyl-2,4-dithioxo-1,3-diazaspiro[4.5]decan-3-yl)spiro[1,5-dihydro-1,5-benzodiazepine-2,3′-indoline]-2′-one). The NMR spectra provided evidence for the tautomeric conversion of the compound. The completely assigned NMR data was supported additionally by ATR.
