TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: Carbodiimide compound is of formula (2-6).R31=substituent optionally substituted with carbodiimide group;n1, n2=1-5;R10, R11, R32=substituent;L3-L6=single bond or divalent connecting group;R3, R4=H or substituent;n3, n4=0-4;m=greater than 2; andAr1, Ar2=coupling group which contains an arylene group. SPECIFIC COMPOUNDS - 14 Compounds (1) are disclosed e.g. compounds of formula (A)-(E).    EXAMPLE - In a reaction container, 500 ml methyl ethyl ketone solution of 100 g cyanuric chloride was cooled to 15 degrees C using nitrogen gas. 60 ml methyl ethyl ketone solution of 116.2 g m-toluidine was dropwise added at 20 degrees C. 272 ml aqueous solution of 138.7 g sodium acetate was dropwise added, and temperature was kept at 25 degrees C. After the reaction, the solution was stirred for 30 minutes, heated to 40 degrees C and stirred for 1 hour. 132.4 g of 2,4-diaminotoluene was added, and the solution was heated to 70 degrees C. The solution was stirred at 70 degrees C for 5 hours, then cooled to 60 degrees C. Water was separated and repeated twice by adding hot water/methyl ethyl ketone solvent to the organic layer. The organic layer was filtered using celite and the solvent was distilled under reduced pressure. 198.0 g product was obtained by crystallizing with ethyl acetate/hexane mixed solvent. 112 ml acetonitrile solution of 8.7 g product, 4.9 g imidazole, and 16.1 g carbon disulfide was added to 300 ml autoclave container, and the inside of a container was filled with nitrogen. The solution was stirred, heated to 100 degrees C, then reacted for 24 hours. The temperature was lowered and ethyl acetate/tetrahydrofuran mixed solution was added. Water was added and liquid separation washing was performed. The organic layer was dried with magnesium sulfate. The solvent was distilled under reduced pressure. 15.5 g product was obtained after washing the solid formed after adding ethyl acetate and boiling. 2.7 ml methanesulfonyl chloride was slowly added dropwise to 300 ml tetrahydrofuran solution of 15 g product, 7.2 ml triethylamine, and 0.2 g N,N-dimethylamino pyridine under water cooling. Loss of raw materials was confirmed with thin layer chromatography, and ethyl acetate/water was added and liquid separated. The solvent was distilled under reduced pressure. 11 g compound (A) was obtained by purifying the reaction product using silica gel column chromatography and crystallizing with methanol.
