Reaction Steps

A solution of 3-bromo-5-chloro-2-pyridinamine (414 mg, 2.0 mmol), phenyl acetylene (225 mg, 2.2 mmol), copper (I) chloride (16 mg, 0.16 mmol), triethylamine (555 μl, 4.0 mmol) and dichlorobis(triphenylphosphine)palladium (II) (32 mg, 0.05 mmol) in DMF (0.5 ml) in a teflon pressure vessel was heated in a microwave (full power) for 30 sec. allowed to cool to RT and reheated for a further 30 sec. After cooling to RT, the reaction mixture was partioned between water—EtOAc, and the organic phase washed with sat. brine, dried oxer MgSO4, and concentrated. Purification by column chromatography on silica gel eluting with methylene chloride-methanol (99:1) and subsequent crystallisation from hexane gave the title compound as a yellow solid (130 mg, 0.6 mmol):
