Reaction Steps

To a solution of tert-butyl 4-((6-(4-formylphenoxy)-5-methylpyrimidin-4-yl)oxy)piperidine-1-carboxylate (950 mg, 0.002298 mole), thiazolidine-2,4-dione (241 mg, 0.00206 mole) and benzoic acid (0.0364 mg, 0.000298 mole) in toluene (30 ml), piperidine (0.033 ml, 0.00344 mole) was added and reaction mixture was refluxed for 7 hours using Dean-Stark apparatus. Then reaction mixture was cooled to 30° C. and solid product was filtered, washed with ice cold toluene and dried to yield 700 mg white solid product.
