実験手順: Methyl cyclododecanecarboxylate was reduced according to Method B2b, Step 1 to give cyclododecylmethanol. The alcohol was converted to cyclododecylmethylbromide according to Method B2b, Step 2. The halide was reacted with 2-hydroxyethylamine according to Method B2b, Step 3 to give N-(2-hydroxyethyl)-N-(cyclododecylmethyl)amine. The alcohol was reacted with SOCl2 according to Method B7a to give N-(2-chloroethyl)-N-(cyclododecylmethyl)ammonium chloride. The chloroethylamine was reacted with 2-methyl-4-nitrophenyl isothiocyanate according to Method C1a to give 2-(2-methyl-4-nitrophenylimino)-3-(cyclododecylmethyl)-1,3 -thiazolidine.

実験手順: To a solution of 9.92 g (50 mmol) of cyclododecane methanol in 100 ml of methylene chloride under a nitrogen atmosphere is added 50 mg of 2,2,6,6-tetramethyl-1-piperidinyloxy, free radical (TEMPO) and 510 mg (5 mmol) of sodium bromide in 5 ml of water. The solution is cooled to 10°-15° C. and a solution of 100 ml of 5.25% aqueous sodium hypochlorite and 2.0 g of sodium bicarbonate is added over 1 hour. The reaction mixture is allowed to warm to room temperature and after 1 hour is diluted with methylene chloride. The organic phase is washed with aqueous sodium thiosulfate, aqueous bicarbonate and water. The methylene chloride layer is dried over magnesium sulfate, filtered and evaporated in vacuo to give 9.43 g of crude title compound as an oil: IR (film) 1723 cm-1 ; NMR (CDCl3)) δ 1.34 (bs, 18 H), 1.41 (m, 4 H), 1.54 (m, 2 H), 1.65 (m, 2 H), 2.40 (m, 1 H), 9.64 (d, 1 H, J=1.6 Hz) M+ (EI) 196 The solution is cooled to 10°-15° C. The organic phase is washed with aqueous sodium thiosulfate, aqueous bicarbonate and water The methylene chloride layer is dried over magnesium sulfate filtered evaporated in vacuo
