الإجراء التجريبي

To a stirred solution of 2-methyltridecan-2-ol 73 (5 g, 23.4 mmol) in Toluene (50 mL) was added triethylamine (3.29 mL, 23.4 mmol)) and followed by 2-bromopropionyl bromide 58 (5.11 g, 23.7 mmol) at 5-10° C. The reaction mixture was stirred for 3 hours at 55-60° C.; the reaction was monitored by TLC. The reaction mixture was quenched with saturated sodium bicarbonate solution and stirred for 15 minutes at 25-35° C. The aqueous and organic layers were separated, the organic layer was washed with brine, and the combined organic layers were washed with brine solution. The organic layer was dried over Na2SO4 and concentrated under vacuum to afford crude 74 (5 g, yield: 61.27%) as a liquid.
