Sodium Hydroxide → 2-(1H-pyrazol-4-yl)-N-(pyridin-2-yl)thiazol-4-amine

Participants

Reaction Steps

According to Scheme 1 Step 10: A solution of N-(2-(1-(4-methoxybenzyl)-1H-pyrazol-4-yl)thiazol-4-yl)pyridin-2-amine (0.39 mmol, 143 mg) in TFA (2 mL) was microwaved for 10 minutes at 120° C. The reaction mixture was neutralized with a solution of NaOH (1 M) and was extracted with DCM. The organic phase was dried over MgSO4, was filtered and was concentrated. The resulting crude product was purified by flash chromatography over silica gel using DCM/EtOH/NH3 (100:0:0 to 90:9:1) as eluent to yield 2-(1H-pyrazol-4-yl)-N-(pyridin-2-yl)thiazol-4-amine (0.24 mmol, 58 mg, 61%) as an orange solid.
