Reaction Steps

A mixture of (S)-ethyl 2-tert-butoxy-2-(7-(4-chlorophenyl)-2-(2-(3-ethylpyrazolo[1,5-a]pyrimidin-6-yl)pyridin-4-yl)-5-methylbenzo[d]thiazol-6-yl)acetate (31 mg, 0.048 mmol) and lithium iodide (200 mg) in pyridine (0.5 mL) was heated in microwave at 170° C. for 1 h. Reaction mixture was diluted with ethyl acetate, washed with 5% acetic acid solution, brine, dried (MgSO4), filtered, concentrated and purified by CombiFlash (0 to 10% MeOH/CH2Cl2). Lyophilization gave desired product.
