The tube was evacuated and refilled with Ar(g) (3 times). 2-Propanol (5.0 mL) and ethylene glycol (0.5 mL, 8.0 mmol) were injected into the schlenk tube. The schlenk tube was sealed with a teflon valve and was heated to 80 C. and stirred for over 24 hours. Subsequently the reaction mixture was allowed to reach room temperature then diluted with EtOAc (10 mL) and water (10 mL). The mixture was acidified of to a pH=3-4 with the addition of 1 M HCl(aq) and the organics were separated and set aside. The aqueous phase was washed with additional EtOAc (10 mL). The combined organic layers were dried over Na2SO4, filtered and concentrated in vacuo affording a yellow solid.
