Participants

Reaction Steps

A 100 mL round bottom flask was charged with tert-butyl 3-(2-(4-methylthiazol-2-ylamino)pyridin-4-yloxy)piperidine-1-carboxylate (1.65 g, 4.23 mmol) in dichloromethane (10 mL), and 2,2,2-trifluoroacetic acid (0.977 mL, 12.7 mmol) was added. The reaction mixture was stirred at room temperature for 2 hours. A saturated solution of NaHCO3 was added, and the solution was extracted with EtOAc and dichloromethane. The combined organic layers were filtered and concentrated to provide 4-methyl-N-(4-(piperidin-3-yloxy)pyridin-2-yl)thiazol-2-amine as a light yellow solid. (0.70 g, 53.6% yield). Mass spectrum (apci) m/z=291 (100) (+H).
