After 2 h the reaction mixture was warmed to room temperature and the solvent was removed on a rotovap. Hexane (100 mL) was added and the solution was extracted with water (50 mL), 20% NaHCO 3 (50 mL) and brine (50 mL). The hexane was dried over MgSO 4, filtered and the solvent was removed on a rotovap. The aliphatic thioesters were purified by .

In 2003 we used the following conditions: 100 degree for 3 min, then 10 deg/min up to 140 the starting 5-bromo-2-pentanone came out at approximately 1.9 min and the product at about 4.5 min. I'd probably try starting at a slightly lower temperature, maybe 80 degrees for 3 min and then ramp up at 20 deg/min to 160 degrees.
