494769-34-5,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.494769-34-5,N-Boc-2-Amino-4-formylthiazole,as a common compound, the synthetic route is as follows.
(c) To a solution commercially available 3-iodopyridine (1.13 g, 5.5 mmol) in 15 mL of THF at 0 C was added a 2M solution of EtMgCl in THF (2.8 mL, 5.6 mmol) dropwise. After 1 h, added a solution of 42b (500 mg, 2.2 mmol) in 5 mL of THF. The reaction was allowed to warm to rt and stirred at for 1 hr. The reaction was quenched with water and extracted 2×EtOAC. The EtOAc extracts were dried over MgSO4, concentrated by rotary evaporator, and chromatographed on SiO2 using 50% hexanes in EtOAc then pure EtOAC to give 336 mg (50%) of 42c. MS found: (M+H)+=308.
494769-34-5 N-Boc-2-Amino-4-formylthiazole 23138686, athiazole compound, is more and more widely used in various fields.
