Reaction Steps

A glass microwave reaction vessel was charged with N-(4-(methoxymethyl)-5-(thiazolo[5,4-c]pyridin-2-yl)thiazol-2-yl)-N-((S)-2-(2-morpholinoethylamino)-3-(4-(trifluoromethyl)phenyl)propyl)acetamide (0.111 g, 0.2 mmol), THF (2.0 mL, 24 mmol), and HCl (2.0 mL, 10 mmol). The reaction mixture was stirred and heated in a Smith Synthesizer® microwave reactor (Personal Chemistry, Inc., Upssala, Sweden) at 150° C. for 12 minutes. The mixture was then made basic with NaOH, extracted with EtOAc, and the organics were adsorbed onto a plug of silica gel and chromatographed through a Redi-Sep® pre-packed silica gel column (4 g), eluting with a gradient of 1% to 10% 2 M NH3.MeOH in DCM, to provide the title compound, 4-(methoxymethyl)-N-((S)-2-(2-morpholinoethylamino)-3-(4-(trifluoromethyl)phenyl)propyl)-5-(thiazolo[5,4-c]pyridin-2-yl)thiazol-2-amine (0.008 g, 8% yield).
