1H NMR, 400 MHz; 13C NMR, 100 MHz; chemical shifts are given in δ values relative to CHCl3 as internal standard and coupling constants in Hz are in parentheses.
These protons appears as very broad multiplets in the proton spectrum. H2-5 and H2-6 data may be interchanged.
Carbon atom multiplicity was deduced by DEPT.
