The reaction was carried out in dry EtOH under an argon atmosphere and at room temperature. NMR spectrum was recorded with a Bruker Avance 300 spectrometer and all chemical shifts are reported relative to the solvent signal [CDCl3: 7.26 ppm ( H)]. The assignments of the NMR signals were carried out under using 2D-NMR experiments H-HCOSY. IR spectra were recorded with a Thermo Nicolet NEXUS FTIR instrument. Elemental analyses (C,H,N,S) were performed with an Elementar Vario EL elemental analyzer. The EI spectra were recorded using Thermo Quest SSQ 710 (70eV). Melting point (m.p.) is measured with a capillary.
