A robust and safe industrial process, including five isolations and drying steps for widely prescribed anti-HIV (protease inhibitor) drug darunavir ethanolate 2, has been developed. A salient feature of this process is the development of procedures enabling the efficient synthesis of multi-kilogram quantity of darunavir ethanolate, and process demonstrations through plant scale preparation are offered where darunavir molecule has been prepared with overall > 70% chemical yield and > 99.8% purity without involving any purification procedure(s), with all possible process impurities below than the desired limit (not more than 0.08%) were isolated, synthesized and characterized. The developed process is entirely robust, very efficient and demonstrated up to kilograms scale.
