(R)-tert-Butyl 4-(3-(5-methoxy-3-(3-methoxypropyl)-3H-imidazo[4,5-b]pyridin-2-yl)piperidin-1-yl)-1-(naphthalen-2-yl)-4-oxobutan-2-ylcarbamate (33E) (0.114 mmol, 0.070 g) prepared according to Example 33, Steps A-E and pyridine hydrochloride (8.65 mmol, 1.00 g) were added to a 15 mL round bottomed flask equipped for stirring under nitrogen. The reaction was subsequently heated to 150° C. and stirred for 15 min. The reaction was cooled to room temperature and water (2 mL) was added. The solution was stirred for 30 minutes at room temperature to allow the solid to completely dissolve. This solution was then filtered and directly purified by preparative LC/MS (10-50% CH3CN in H2O). The resultant fractions were collected and the solvent was removed in-vacuo affording the title compound as a clear colored oil (0.004 mmol, 0.002 g, 3% yield). ESI-MS: m/z 502.2 (M+H)+.
