2,4-피페라딘디온 C화학적 특성, 용도, 생산
개요
2,4-Piperidinedione is an important piperidine ring-containing intermediate, and its 2,4-piperidinedione, as a characteristic fragment, is widely used as an intermediate in the synthesis of ibrutinib and paliperidone drugs.
화학적 성질
White to light yellow solid
제조 방법
The synthesis of 2,4-Piperidinedione involved dissolving 400 mg (2.34 mmol, 1.00 eq.) of Methyl 2,4-dioxo-piperidine-3-carboxylate in a mixture of acetonitrile (20 mL) and water (0.2 mL). The solution was then heated to approximately 86° C. and maintained at this temperature for around 4 hours. After completion of the reaction, the solvent was removed under vacuum, leaving behind a residue of 2,4-Piperidinedione. This residue was further purified using silica gel column chromatography with a mobile phase consisting of dichloromethane and methanol in a ratio of 100:1. The target product, 2,4-Piperidinedione, was obtained as a white solid, with a yield of 27%, corresponding to 70 mg.
