30% | With hydrogenchloride;aluminium trichloride; In dichloromethane; | EXAMPLE 1 2-(4-Methoxy-2,3,6-trimethylbenzoyl)-5-nitrothiazole One gram of 5-nitrothiazole-2-carboxylic acid chloride in 10 ml. of methylene chloride is combined with 850 mg. of <strong>[20469-61-8]<strong>[20469-61-8]2,3,5-trimethylanisol</strong>e</strong> and then with 1.6 g. of aluminum chloride. After three hours of agitation at room temperature, the reaction mixture is poured on 50 ml. of 1N HCl and extracted with ethyl acetate. After drying of the solution and evaporating the solvent under vacuum, the crystalline residue is recrystallized from methanol/chloroform. Yield: 30%; m.p. 125-126 C. |

5.0 g (67.0%) | With chlorosulfonic acid; In dichloromethane; | (2) Synthesis of 4-methoxy-2,3,6-trimethylbenzensulfonyl chloride In 500 ml of methylenchloride was dissolved 4.5 g of <strong>[20469-61-8]<strong>[20469-61-8]2,3,5-trimethylanisol</strong>e</strong>, and after cooling at -5~-10 C., a solution (400 ml) of 6.0 ml of chlorosulfonic acid in methylene chloride was added dropwise to the mixture. The reaction mixture was kept at room temperature and then poured into ice-5% aqueous NaHCO3. The methylene chloride layer was washed with water and dried over anhydrous magnesium sulfate. The solvent was distilled off and the residue was crystallized from n-hexane and filtered. Yield 5.0 g (67.0%), m.p. 56-58 C.

5.0 g (67.0%) | With chlorosulfonic acid; In dichloromethane; | (2) Synthesis of <strong>[20469-61-8]4-methoxy-2,3,6-trimethylbenzene</strong>sulfonyl chloride In 500 ml of methylene chloride was dissolved 4.5 g of <strong>[20469-61-8]<strong>[20469-61-8]2,3,5-trimethylanisol</strong>e</strong> and the solution was cooled to -5 C. to -10 C. A solution of 6.0 ml of chlorosulfonic acid in 400 ml of methylene chloride was added dropwise, and then the temperature was allowed to rise to room temperature. The mixture was poured into an ice--5% aqueous sodium hydrogen carbonate mixture. The methylene chloride layer was washed with water and dried over anhydrous magnesium sulfate. The solvent was then distilled off, and the residue was crystallized from n-hexane. Yield 5.0 g (67.0%). m.p. 56-58 C. |
