Participants

Reaction Steps

To a solution of tert-butyl 4-{2-[(1R)-1-hydroxyethyl]-1H-imidazo[4,5-d]thieno[3,2-b]pyridin-1-yl}piperidine-1-carboxylate (71 mg, 0.18 mmol) in methylene chloride (1.2 mL) was added 4.0 M hydrogen chloride in dioxane (0.35 mL, 1.4 mmol). The reaction solution was stirred at room temperature for 6 h. The solvent was removed to give the desired product as white solid (60 mg, 100%). LCMS calculated for C15H19N4OS (M+H)+: m/z=303.1. Found: 303.1.
