Reaction Conditions

Reaction Steps

4-Chloro-3-nitropyridine (100 mg, 0.630 mmol) and cyclopropyl boronic acid (10.0 mg, 0.091 mmol) were added to a solution of xylene (3 mL) previously purged with argon (10 min). The reaction mixture was purged with argon for a further 15 mins, followed by the addition of potassium carbonate (174.35 mg, 1.26 mmol) and Pd(PPh3)4 (34.5 mg, 0.063 mmol). The resulting mixture was heated to reflux at 130° C. overnight. The reaction was monitored by TLC (30% ethyl acetate in hexane). The reaction mixture was cooled and concentrated to afford the crude product. Purification by column chromatography on silica gel (15% ethyl acetate in hexane) afforded 110 mg of the product (100% yield). LCMS: 99.09%, m/z=165 (M+1)
