Procedure

500 mg (1.6 mmol) of 2,2-Dimethyl-octadecanoic acid (Roth, Bruce D. et al., J. Med. Chem. 1992, 35(9), 1609-17) were dissolved in anhydrous dichloromethane (10 ml), and 350 mg (1.8 mmol) of dicyclohexylcarbodiimide (DCC), and 140 μl (2 mmol) of 2-bromoethanol were added thereto, followed by stirring of the mixture at room temperature overnight. The reaction mixture was purified using a silica gel column (elution by hexane-ethyl acetate (7:1) solvent mixture) to obtain 230 mg of 2-(2,2-dimethyloctadecanoyloxy)ethyl bromide to be used below.
