Versuchsvorschrift

Tetrakis (triphenylphosphine) palladium (33 mg, 0.0288 mmol) was added to potassium carbonate (120 mg, 0.8649 mmol) previously purged with argon (30 minutes). The reaction mixture was purged with argon for 15 minutes, followed by the addition of 1-(4-chloro-thieno[3,2-c]pyridin-2-yl)-3-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (98A: 100 mg, 0.2883 mmol) and methyl boronic acid (21 mg, 0.3459 mmol). The reaction mixture was heated to reflux for 6 hours. The reaction was monitored by TLC (10% MeOH in CHCl3). The reaction mixture was concentrated to afford the crude product. Purification by column chromatography on silica gel (3-4% MeOH in CHCl3), followed by preparative HPLC afforded 10 mg of the product (16.39% yield).
