Reaction Steps
To a solution of 25% NaOMe/MeOH (23 ml, 0.10 mol) and ethanol (27 ml) are added thiourea (5.33 g, 0.70 mol) and ethyl 4,4,4-trifluoroacetoacetate (7.3 ml, 50 mmol), then the reaction is heated to reflux for 16 hrs. The mixture is cooled to 22° C., concentrated in vacuo, and the residue dissolved in water (50 ml), acidified with HCl (7 ml), and filtered. The solid is collected, washed with water, and dried: 6.58 g (32.5 mmol, 65%).
