1-(4-Chloro-thieno[3,2-c]pyridin-2-yl)-3-(4-methyl-pyridin-3-yl)-imidazolidin-2-one → 1-(4-Methyl-pyridin-3-yl)-3-thieno[3,2-c]pyridin-2-yl-imidazolidin-2-one

Participants

Reaction Steps

10% Pd-C (10 mg) was added to a solution of 1-(4-chloro-thieno[3,2-c]pyridin-2-yl)-3-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (98A: 80 mg, 0.232 mmol) in methanol (10 mL) under nitrogen atmosphere. The resulting mixture was hydrogenated at 30 PSI (2.04 atm) for 12 hours at room temperature. The reaction was monitored by TLC (10% MeOH in CHCl3). The reaction mixture was filtered through celite bed, washed with methanol and the filtrate was concentrated under reduced pressure to afford the crude product. Purification by preparative TLC afforded 10 mg of the product (14% yield).
