Acetyl chloride → HCID 66701188, compound

Participants

Reaction Steps

The synthesis was carried out analogously to the synthesis of amine AMN-07. For this, in step (i) tert-butyl 2,8-diazaspiro[5.5]undecane-2-carboxylate was reacted with 4-chloropyridinium chloride (yield: 66%). The Boc protective group was then split off. In step (ii), ethanol (8 ml) and acetyl chloride (0.45 ml, 6.335 mmol) were added to tert-butyl 8-(pyridin-4-yl)-2,8-diazaspiro[5.5]undecane-2-carboxylate (0.42 g, 1.267 mmol) and the mixture was stirred at room temperature for 12 h. When the reaction was complete, the solvent was removed in vacuo. Yield: 0.39 g (90%)
