According to Scheme 5 Step 2: A solution of N-(4-(1-(4-methoxybenzyl)-1H-pyrazol-4-yl)-5-bromothiazol-2-yl)pyridin-2-amine (2.16 mmol, 1.00 g), piperidine (8.64 mmol, 0.89 mL) and Et3N (12.9 mmol, 1.81 mL) in DMF (10 mL) was microwaved for 30 minutes at 150° C. The reaction mixture was diluted with AcOEt and water. The aqueous phase was extracted with AcOEt. The organic phase was dried over Na2SO4, was filtered and was concentrated to yield N-(4-(1-(4-methoxybenzyl)-1H-pyrazol-4-yl)-5-(piperidin-1-yl)thiazol-2-yl)pyridin-2-amine (0.58 mmol, 263 mg, 26%) as a beige solid.
