Participants

Reaction Steps

K2CO3 (3.1 mmol/0.34 g) is added to undissolved N-{4-[5-(4-fluorophenyl)-3-methyl-2-thioxo-2H-imidazol-4-yl]pyridin-2-yl}acetamide (2.23 mmol/0.8 g), and the mixture is then suspended in 100 ml of absolute acetone. Ethyl 3-bromopropionate (2.3 mmol/0.422 g) are then added, and the mixture is stirred at room temperature for 24 h. The mixture is then heated under reflux for 3 h, the precipitate is filtered off and the filtrate is concentrated under reduced pressure using a rotary evaporator. The oily residue is separated on a column (mobile phase: CH2Cl2/EtOH, 9.5:0.5).
