Morpholine → HCID 86743564, compound

Participants

Reaction Steps

Crude bis (2,2-dimethyl-3-oxopropyl) maleate was treated with a catalytic amount of morpholine (10 wt. %) in refluxing toluene for 4 hrs. The resulting solution was cooled to room temperature, washed with diluted hydrochloric acid and brine, then dried over magnesium sulfate. Evaporation of volatiles in vacuo gave crud bis (2,2-dimethyl-3-oxopropyl) fumarate in essentially quantitative yield. NMR* (CDCL3): 9.7 (s, 1H,--CHO), 6.93 (s, 2H, trans --CH=CH--), 4.33 (s, 2H, --CO2CH2 --), and 1.2 (s, 6H, --C(CH3)2 --).
