실험 절차

A mixture of 2-hexadecanoyloxy-1-(hexadecanoyloxymethyl)ethyl 4-chloroformyl-3,3-dimethylbutyrate (F) (1.5 g.), triclosan (0.4 g.) and pyridine (0.17 ml.) in methylene chloride (35 ml.) was stirred at 0°-5° C. for 3 hours and then allowed to attain ambient temperature during 45 hours. The methylene chloride was evaporated and replaced by ether (50 ml.). The mixture obtained was washed successively with water (3×20 ml.), 2M hydrochloric acid (25 ml.), saturated sodium hydrogen carbonate solution (2×20 ml.) and water (2×20 ml.), and then dried (MgSO4) and evaporated. The oil obtained crystallised on treatment with ethanol to give 5-chloro-2-(2,4-dichlorophenoxy)phenyl 4-[2-hexadecanoyloxy-1-(hexadecanoyloxymethyl)ethoxycarbonyl]-3,3-dimethylbutyrate as white crystals (0.3 g.), (m.p. just below 20° C.); NMR (CDCl3): 0.7-1.0 (6H, m, CH3CH2), 1.12 (6H, s, CCH3), 1.15-1.7 (52H,m, CH2), 2.17 (4H, m, CH2CH2CO), 2.44 (2H,s, CH2CO2CH), 2.60 (2H, s, aromatic O.CO CH2), 3.9-4.4 (4H, m, CH2O), 5.1-5.4 (1H, m, CH2CO2CH), 6.9-7.5 (6H, m, aromatic H)ppm.
