Procedure

Anhydrous potassium carbonate (110 mg, 0.8 mmoles) was added to a solution of N-(6-((trimethylsilyl)ethynyl)pyridine-2-yl)acetamide (1.86 g, 8 mmol) in 20 ml anhydrous methanol. The reaction mixture was stirred at room temperature for fifteen minutes then filtered. The filtrate was concentrated in vacuo. The crude product mixture was chromatographed on Silica Gel (230-400 Mesh) eluting with 2.5% MeOH/98% CH2Cl2 to yield A436.1 as an off-white solid. (770 mg, 60% yield). M+H+=218.20 1H NMR (400 MHz) MEOD δ 8.13 (m, 1H), 7.75 (m, 1H), 7.27 (m, 1H), 3.65 (s, 1H), 2.18 (s, 3H).
