D8 quest instrument

¹H-NMR, ¹³C-NMR, HOMO-COSY, and HSQC spectra were obtained using BRUKER 400 MHz with TMS as the internal standard and CDCl₃ as the solvent. AGILENT 6550 Q-TOF LC-MS (HRMS) was used for recording mass spectra. FT-IR was carried out using an AGILENT Cary 630 spectrophotometer. The spectra were recorded in the range between 400 to 4000 cm⁻¹ using KBr pellets. Purity of the compound was confirmed using TLC and HPLC. For HPLC, an AGILENT 1260 Infinity high performance liquid chromatography system was used. X-ray data for the compound were collected at room temperature on a Bruker D8 QUEST instrument with an IμS Mo micro source (λ = 0.7107 A) and a PHOTON detector. The raw data frames were reduced and corrected for absorption effects using the Bruker Apex 3 software suite of programs.⁴⁵ The structure was solved using the intrinsic phasing method and further refined with the SHELXL program and expanded using Fourier techniques.^{46 (link)} Anisotropic displacement parameters were included for all non-hydrogen atoms. All C bound H atoms were positioned geometrically and treated as riding on their parent C atoms (C–H = 0.93–0.97 Å, and U_iso(H) = 1.5U_eq(C) for methyl H or 1.2U_eq(C) for other H atoms).⁴⁷ The CCDC deposition number is 2117832.†
