This was filtered, the filter cake washed with additional IPA, and the filtrate and washes combined and the solvent removed under vacuum. This was dissolved in 100 mL of dilute H2SO4, which was washed with 2x50 mL CH2Cl2. The aqueous phase was made basic with sodium hydroxide, extracted with 2x50 mL CH2Cl2, and the extracts pooled, dried over anhydrous K2CO3, and stripped of solvent under vacuum to yield a nearly colorless residue. There was perhaps a brush of light-headedness at the third hour point, but other than that, nothing. No effect that can be ascribed to today's drug trial.
Nothing comes to mind.
This, along with most of the di- and triethylated thiomescaline analogues, represents a lot of synthetic effort without useful qualitative data.
