Reaction Steps

A glass microwave reaction vessel was charged with N-((S)-2-amino-3-(3-chlorophenyl)propyl)-N-(4-(methoxymethyl)-5-(thiazolo[5,4-c]pyridin-2-yl)thiazol-2-yl)acetamide (0.090 g, 0.1 8 mmol), THF (2.0 mL, 24 mmol), and 5 N HCl (2.0 mL, 10.0 mmol). The reaction mixture was stirred and heated in a Smith Synthesizer® microwave reactor (Personal Chemistry, Inc., Upssala, Sweden) at 150° C. for 11 minutes. The solution was then made basic with 10 N NaOH and extracted with EtOAc. The solvent was removed, and the compound was purified by reverse phase HPLC to give the title compound (31 mg, 38%).
