Chlorotrimethylsilane (10.00 mL, 78.79 mmol) was added and the reaction was stirred at room temperature for 4 days. The reaction was checked by LC-MS with the product mass [M+H]+ 201 seen. The mixture was concentrated under reduced pressure. The resulting residue was diluted with dichloromethane (200 mL). The organic layer was then washed with saturated NaHCOa, dried over sodium sulfate, filtered and concentrated under reduced pressure to give a slightly viscous, clear and colorless oil. The oil was redissolved in anhydrous THF and concentrated to yield 49.5 g (95%) of cyclohexane- l ,3-dicarboxylic acid dimethyl ester, which was used in the next step without further purification.

YieldReaction ConditionsOperation in experiment
With 1,3-dimethyl-2-imidazolidinone; ammonia; tin(II) oxide; at 210 - 280℃; for 9h; A four-neck flask equipped with a stirrer, a gas inlet tube, a thermometer, a gas purge line, and a condenser was charged with 15.1 g of 1,3-cyclohexanedicarboxylic acid obtained in the same manner as in Example 2, 17.4 g of <strong>[62638-06-6]dimethyl 1,3-cyclohexanedicarboxylate</strong>, 5.0 g of N,N?-dimethylimidazolidinone (boiling point 226 C.), and 0.40 g of tin (II) oxide, and the mixture was heated to 210 C. while stirring at 250 rpm. [0189] Thereafter, ammonia gas was introduced at a rate of 72 mL/min (1.1 mol equivalent/1,3-cyclohexanedicarboxylic acid +<strong>[62638-06-6]dimethyl 1,3-cyclohexanedicarboxylate</strong>/hr). The temperature inside the reactor was kept at 210 C. for 1 hour, and then thereafter, increased to 280 C.: while the temperature was kept constant, reaction was performed. After 8 hours, the reaction was terminated, and the reaction product was cooled to 90 C. When the reaction was terminated, almost no white solid was observed in the gas purge line and the condenser. [0190] Then, 31.6 g of 1-butanol was added thereto and the mixture was stirred to produce a reaction mixture. The reaction mixture was filtered by hot filtration to remove the catalyst. The filtrate was analyzed by gas chromatography, and it was found that the conversion of 1,3-cyclohexanedicarboxylic acid was 100%, the conversion of dimethyl 1,4-cyclohexanedicarboxylate was 99%, the yield of 1,3-dicyanocyclohexane was 86%, and the trans isomer/cis isomer ratio was 47/53. [0191] Then, the solvent was distilled off from the filtrate obtained as described above and the filtrate was dried, thereby producing a yellow solid. The yellow solid was analyzed by gas chromatography, and it was found that solid was 1,3-dicyanocyclohexane having a purity of 96.1%. [0192] A metal (tin) content of the solid was 10 ppm or less, which was 9.61 (10×0.961) ppm or less relative to 1,3-dicyanocyclohexane (including trans isomer and cis isomer).
