YieldReaction ConditionsOperation in experiment
With toluene-4-sulfonic acid; In Methyl isobutyl carbinol; for 5.0h;Heating / reflux; Preparation of the Compound of Example No. 46 by Reacting 4 with 9; A suspension of 201 g (1.06 mol) para-toluenesulphonic acid-hydrate, 209 g (706 mmol) 9 and 183 g (695 mmol) 4 in 800 mL 2-methyl-4-pentanol is refluxed. 100 mL solvent are distilled off. The mixture is refluxed for 3 hours, 200 mL of 2-methyl-4-pentanol are added and 120 mL of solvent are distilled off. After 2 hours heating at reflux temperature a further 280 mL solvent are distilled off. The mixture is cooled to 100 C. and 1 L demineralised water and then 0.5 L ethyl acetate are added to the reaction solution. The organic phase is separated off and the aqueous phase is again washed with 0.5 L ethyl acetate. 1.5 L dichloromethane and 0.5 L ethyl acetate are added to the acidic aqueous phase. The pH value of the aqueous phase is adjusted to pH 9.2 with 260 mL of 6 normal sodium hydroxide solution. The aqueous phase is separated off and the organic phase is washed three times with in each case 1 L of 1 normal aqueous sodium hydrogen carbonate solution. The organic phase is dried over sodium sulphate, filtered and the solvent is evaporated down under reduced pressure. 406 g of crude product are obtained.The crude product is dissolved in 1.5 L ethyl acetate. At a temperature of 50-55 C. 2.5 L of methyl-tert.-butylether are added. The mixture is inoculated at 45 C. and stirred for 16 hours with cooling to ambient temperature. The suspension is stirred for 3.5 hours at 0-5 C. and the precipitate is suction filtered. The filter cake is washed again with methyl-tert.-butylether/ethyl acetate (2:1) and methyl-tert.-butylether. The product is dried at 50 C. in the vacuum drying cupboard. 236 g of crystalline compound of Example no. 46 are obtained as the anhydrate (I).
