With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.144690-92-6,Triphenyl methyl olmesartan,as a common compound, the synthetic route is as follows.,144690-92-6
Trityl olmesartan medoxomil (8 g, 10 mmol) is added to a mixture of acetone (35 ml) and water (10 ml). To the resulting suspension 37 % aqueous hydrochloric acid (2.5 ml, 30 mmol) is added. The mixture is then stirred at room temperature for 4 h. Water (130 ml) is added and the mixture is stirred for additional 30 minutes. The precipitated triphenylmethanol is filtered off. The filtrate is concentrated in vacuum at 40 C to 100 ml, and then stirred vigorously for 1 h at room temperature and then additional 30 minutes at 0 C. The precipitate is filtered to give 4.7 g of olmesartan medoxomil hydrochloride Form A (98.3 % area)
The synthetic route of 144690-92-6 has been constantly updated, and we look forward to future research findings.
