Chemical Products Candesartan Production Methods
To the product obtained in Step A) (350 g) dissolved in methanol (1.17 L) was added sodium hydroxide solution (93 g in 1.17 L water). The reaction mass was heated to reflux at 78-80°C and maintained for 1 hour. After completion of reaction, methanol was completely removed under vacuum at 40-45°C and to the residue was added ethyl acetate (2. 8 L) and water (3.50 L) at room temperature. Stirred the mixture for about 1 hour at 25- 30°C and allowed to settle for 15 minutes. Separated the layers and pH of the aqueous layer was adjusted to 4-5 with acetic acid (about 450 g) at 10-15°C. The precipitated product was filtered and washed twice with water (2 x 0.7 L) and suck dried. The wet cake was air dried at room temperature for 2 hours and then at 50-55°C to afford the title compound.
