144690-92-6,is a common compound. C48H44N6O6.In an article, once mentioned the new application about 144690-92-6.
Example 4; Olmesartan medoxomil (V); The starting substance (III; 10 g) was dissolved in acetone (50 ml), and, after adding water (25 g), the mixture was heated to a mild boil for 14 h. After evaporating acetone and adding ethyl acetate (50 ml), water was separated, and the organic layer was again washed with water (10 ml). The extract was concentrated and evaporated with toluene (50 ml) once more, the residue was dissolved in ethyl acetate (20 ml) and toluene (20 ml). The mixture was concentrated to 25 ml and allowed to crystallize under stirring for 30 min; after cooling to 15 C, the insoluble portion was sucked off and washed with ethyl acetate. 6.5 g of the product was obtained, which, after recrystallization from ethanol, gave 6 g (86 %) of the product with an HPLC purity of 98.7 %.By further recrystallization from ethyl acetate and cyclohexane, 5.1 g of a sample with an HPLC purity of 99.6 % was obtained. 1H NMR (250 MHz, CDCl3) delta: 0.82 (3H, t, J = 7.5 Hz); 1.50 (6H, s); 1.54-1.63 (2H, m); 2.07 (3H, s); 2.48 (2H, t, J = 7.5 Hz); 4.86 (2H, s); 5.32 (2H, s); 6.70 (2H, d, J = 8 Hz); 6.99 (2H, d, J = 8 Hz); 7.3-7.5 (3H, m); 7.72 (IH, dd, J = 1.7 Hz).
