A Facile Synthesis of Raltegravir Potassium—An HIV Integrase Inhibitor

A facile, cost-effective, and commercially viable synthesis of Raltegravir Potassium (1) has been developed from 2-(1-amino-1-methyl-ethyl)-N-[(4-fluorophenyl)methyl]-1,6-dihydro-5-hydroxy-1-methyl-6-oxo-4-pyrimidinecarboxamide (9) with high purity and in good yields. In addition, a new approach for the synthesis of key amine intermediate (9) of Raltegravir Potassium (1) from commercially available 2-amino-2-methylpropanenitrile hydrochloride (2) is also described. The key features of the synthesis are fewer synthetic steps, employing the inexpensive reagents and eco-friendly.

Preparation method of pyrimidinone amide type compound

The invention discloses a pyrimidinone amide type compound and a preparation method thereof. A pyrimidinone compound is taken as a starting material and is subjected to four-step chemical conversion to obtain TN-A005 and an analogue thereof, and an intermediate can be prepared from methyl tetrazole. A one-pot method is used for feeding in the whole preparation process, post-treatment purificationof each step is recrystallization or dispersion washing, the use of means such as silica gel column chromatography is avoided, the preparation technology is greatly simplified, the preparation efficiency is improved, and the total yield can reach 50%. The method is simple and convenient in preparation steps and can improve the preparation efficiency.
