Trifluoroacetic acid → 6-(2,8-Diazaspiro[4.5]decan-8-yl)isoquinoline trifluoroacetate

Participants

Reaction Steps

TFA (2 ml) was added to a cooled (0° C.) solution of tert-butyl 8-(isoquinolin-6-yl)-2,8-diazaspiro[4.5]decane-2-carboxylate (0.544 mmol, 1.0 eq.) in methylene chloride (10 ml) and the reaction mixture was stirred at room temperature for 1 h. When the reaction was complete, the solvent was removed on a rotary evaporator. The crude product was employed directly in the next step.
