Unless stated otherwise, all reactions were carried out using standard
Schlenk techniques in a dry nitrogen atmosphere. Dry solvents were
purchased from Merck or Across and used as received. Glassware was
oven-dried at 110 °C prior to its use. NMR spectra were recorded
on a Bruker AVANCE I 300 MHz, AVANCE II 500 MHz or AVANCE III 600
MHz with cryo-probehead instrument in deuterated solvents (Eurisotop)
at 25 °C. Chemical shifts are reported in ppm and were referenced
using the residual solvent signal. High-resolution electrospray ionization
time-of-flight mass spectrometry (ESI-TOF MS) was performed on an
ESI-(Q)-TOF-MS MICROTOF II (Bruker Daltonics) mass spectrometer. 2,6 Bis(hydroxymethyl)-4-iodopyridine was synthesized according
to literature procedure.27 (link)
