Procedure

4.45 g of potassium hydroxide 85% are suspended in 40 mL of DMF, 4.37 g of methyl 3-oxopentanoate (0.036 mol) are subsequently added. The reaction mixture is warmed to 50° C. and 6 mL of 2,3-dichloro-5-(trifluoromethyl)pyridine are introduced. The reaction mixture is stirred at 50° C. for 4 hours, quenched with 150 mL of an aqueous solution of NaH2PO4 (1M), extracted thrice with 150 mL of ethyl acetate.
