Sodium Carbonate → Tert-butyl 4-(1-[5-(3-aminophenyl)-1,3-thiazol-2-yl]-1-hydroxyethyl)piperidine-1-carboxylate

Participants

Reaction Steps

The product of Step 2 (87 mg, 0.222 mmol), 3-aminophenylboronic acid monohydrate (41.3 mg, 0.267 mmol), Pd(Ph3P)4 (12.85 mg, 0.011 mmol) and Na2CO3 (0.333 mL, 0.667 mmol) were stirred in DME at 100° C. overnight under N2. The reaction mixture was filtered through a pre-pack pad of celica with dichloromethane. The filtrate was concentrated and the residue was purified by flash chromatography to give tert-butyl 4-{1-[5-(3-aminophenyl)-1,3-thiazol-2-yl]-1-hydroxyethyl}piperidine-1-carboxylate (82.4 mg, 0.204 mmol, 92%) as a yellow oil.
