I have a proton value at 8.07ppm and carbon 167ppm correlate to a CH proton I think it's a proton at 3 position of a indole. Is it viable? Seems like the 13C is too deshielded...

I used to measure many spectra of indoles and their derivatives, even nitroindoles don't show such hicgh chemical shift of 13C. The given value is tipycalliy amide or ester chemical shift. In my experience, even heteroaromatic carbons cannot reach these values.
