YieldReaction ConditionsOperation in experiment
91% To a solution of the thiazole acid derivative (6.46 g, 50.0 mmol) and THF (100 mL) at 0 °C was added CDI (9.72 g, 60.0 mmol) in one portion. The mixture was then stirred at r.t. for 4 hours. In a separate flask, a mixture of ethyl potassium malonate (25.5 g, 150 mmol),MgCl (14.3 g, 150 mmol), and THF (100 mL) was stirred at 75 °C for 4 hours. Upon completion of the two reactions, the mixture containing activated acid derivative was added to the other flask at r.t. The combined reaction mixture was stirred at 50 °C for 16 hours. The mixture was cooled to r.t. and 2M HC1(aq) (100 mL) was added. The mixture was extracted with ethyl acetate (2 x 150 mL), washed with sat. NaHCO3, brine and filtered through a silica gel plugto afford the desired f3-ketoester product as a brown oil (9.11 g; 9 1percent).
