Procedure

To a stirred solution of 1-decanol 2 (10 g, 53.7 mmol) in toluene (100 mL) was added triethylamine (7.5 mL, 53.7 mmol)) and followed by 2-bromo propionyl bromide 58 (12.7 g, 59.1 mmol) at 5-10° C. The reaction mixture was stirred for 3 hour at 55-60° C., and 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 combined organic layers were washed with brine solution. The organic layer was dried over Na2SO4 and concentrated under vacuum to afford crude 59 (16.19 g, yield: 94%) as a liquid.
