YieldReaction ConditionsOperation in experiment
19% 5-Bromo-4-methylpyridin-2,3-diamine2 (0.50 g, 2.5 mmol) was dissolved in DMF (7.0 [ML).] Iron (III) chloride hexahydrate (0.033 g, 0.12 mmol) was added and the mixture heated to [80 C. 4- (2-PIPERIDIN-I-YLETHOXY) BENZALDEHYDE] (0.58 g, 2.5 mmol) dissolved in DMF (3.0 ml) was added dropwise. and the reaction mixture was heated at [120 C] for 5 h with air bubbling through the solution. The solvent was removed by evaporation and the solid residue was washed with [1M NAOH] and diethyl ether. The crude product was purified by column chromatography (EtOAc/heptane, 1: 1), giving the title product (0.20 g, 19%).

YieldReaction ConditionsOperation in experiment
With potassium hydroxide; In ethanol; water; at 20℃; for 2h; General procedure: To a solution of 2-12 in ethanol (100 mg, 0.62 mmol, 13 ml/mmol) was added the suitably functionalized benzaldehydes (0.62 mmol), followed by a solution of KOH 20% in water (0.8 ml/mmol). The solution is stirred at room temperature for 2 h. The reaction mixture was concentrated in vacuo and diluted with distilled water. The aqueous layer was extracted with ethyl acetate and dried (Na2SO3). The organic phase was evaporated in vacuo to yield crude products which were subjected to column chromatography by using amino silica gel as adsorbent and solvent system of hexane: ethyl acetate (7:3) followed by silica gel column chromatography by using chloroform: methanol (9.5:0.5) to yield Series 2 derivatives except for 2-6 and 2-9.
