The mechanism of the selective demethylation of 13 is unclear. Nevertheless, we have reported that the partial demethylation of 18 with BBr3 (2 equiv) at -78 °C afforded phenol 19 (72%), the structure of which was confirmed by X-ray crystallographic analysis (Scheme 4). See

As far as we know, there is no report of any spectroscopic data of 17 in the literature. Because 17 was difficult to isolate in its pure form, its spectroscopic data were measured after the usual work-up
