実験手順
A mixture of 103.0 mmol 1-(2-ethyl-butyl)-cyclohexanecarboxylic acid, 38.9 mmol cyclo-hexanecarboxylic acid and 100 μL triethylamine (0.72 mmol=0.005 eq. relative to the sum of both acids) was warmed to 50° C. 12.4 mL (170.3 mmol=1.2 Eq. relative to the sum of both acids) of thionyl chloride was added during 22 minutes at a temperature of 41-51° C. (reaction is endothermic, vigorous gas evolution) and the reaction mixture was kept at 54-55° C. After 10 minutes the reaction was almost complete (0.13% 1-(2-ethyl-butyl)-cyclohexanecarboxylic acid and 0.13% 1-(2-ethyl-butyl)-cyclohexanecarboxylic acid anhydride). After 1.5 hr the reaction was complete (0.04% 1-(2-ethyl-butyl)-cyclohexanecarboxylic acid and no 1-(2-ethyl-butyl)-cyclohexanecarboxylic acid anhydride). After removing volatile components in vacuo (60° C. bath, 3.5-4.3 mbar followed by 120° C. bath, 10-11 mbar) 26.19 g of residue was obtained (assay 92.9% 1-(2-ethyl-butyl)-cyclohexanecarbonyl chloride, yield 100%).
