EXAMPLE 10 STR124 1.9 l of sodium hypochlorite (about 150 g of active chlorine per liter) were added slowly to a solution of 175 g (1 mole) of 2-methylmercapto-4-methyl-6-chloropyrimidine in 375 ml of concentrated hydrochloric acid and 375 ml of water at 5 C. The product which had precipitated was then filtered off and rinsed with water. This gave 170 g (82% of theory) of 2-methylsulfonyl-4-methyl-6-chloropyrimidine in the formn of colorless crystals of melting point 72 C. STR125

Here is a compound 17119-73-2, name is 4-Chloro-6-methyl-2-(methylthio)pyrimidine. This compound has unique chemical properties. The synthetic route is as follows.

[00195] Ethyl 3-iodo-i-methylcyclopentanecarboxylate (5.60 g, 19.9 mmol) was dissolved in dimethylacetamide (66 mL) in a pressure vessel under a stream of nitrogen. Rieke Zinc (28.6 mL of a 5Omg/mL suspension in THF, 21.8 mmol) was added quickly via syringe. The vessel was capped and stirred at ambient temperature for 15 minutes. The vessel was opened under a stream of nitrogen and 4-chloro-6-methyl-2- (methylthio)pyrimidine (4.16 g, 23.8 mmol) was added followed by PdCl2dppf (1.09 mg, 1.49 mmol). The vessel was capped and heated to 80 C for 2 h. The reaction mixture was then cooled to room temperature, diluted with ethyl acetate, and filtered through celite. The filtrate was transferred to a separatory funnel and washed with water (3x), brine, and dried over sodium sulfate. The dried solution was filtered, and the filtrate was concentrated. The residue was purified by flash-column chromatography on silica gel (gradient elution, 0 to 100% ethyl acetate-hexanes) to give ethyl 1-methyl- 3 -(6-methyl-2-(methylthio)pyrimidin-4-yl)cyclopentane- 1 -carboxylate (2.1 g, 36%) as a mixture of cis and trans isomers. The isomers were separated by preparative HPLC (column: Phenomenex Gemini C18 250*5Omm*10 um; mobile phase: 45-70% water [0.05% ammonia hydroxide v/v]-ACN) to give ethyl (1R,3R and 1S,3S)-1-methyl-3-(6- methyl-2-(methylthio)pyrimidin-4-yl)cyclopentane- 1 -carboxylate (700 mg) as a colorless oil.
