(1-Azabicyclo[3.3.0]octan-5-yl)acetyl chloride hydrochloride (2.00 g, 8.93 mmol) was added to a solution of 2-(3,7,11,15,19,23,27,31,35,39-decamethyl-2,6,10,14,18,22,26,30,34,38-tetracontadecaen-1-ylthio)ethylamine (5.00 g, 6.61 mmol, prepared as described in Example 4) in 75 ml of pyridine at the temperature below 20° C. and the solution was stirred at 25° C. for 3 hours. (1-Azabicyclo[3.3.0]octan-5-yl)acetyl chloride hydrochloride (0.9 g, 4.02 mmol) was further added to the reaction mixture at the temperature below 20° C. and the solution was stirred at 25° C. for an hour. The solvent in the reaction mixture was evaporated in vacuo to dryness and the remaining residue was partitioned between chloroform and 10% sodium hydroxide aqueous solution. The organic layer was washed with saturated sodium chloride aqueous solution, dried over anhydrous sodium sulfate, filtered and evaporated in vacuo to dryness to give a brown residue. The residue was chromatographed on silica gel, eluting with CH2Cl2 /MeOH (10:0-10:1.5) to afford 5.2 g (86.7%) of the desired compound, as a colorless oil.
