Reaction Steps

tert-Butyl 6-(2-(piperidin-1-yl)ethoxy)-3,4-dihydro-1H-pyrido[4,3-b]indole-2(5H)-carboxylate (1.33 g, 3.32 mmol) was added to HCl in MeOH (reagent 10, 25 ml) at 25° C. under air. The resulting solution was stirred at room temperature for 3 days. The solvent was removed under reduced pressure to afford (1.00 g, 100%) as a yellow gum. Material was used crude.
