実験手順
A mixture of 160 mg (0.63 mmol) of 2-(morpholin-4-yl)-3-trifluoromethyl-5-bromopyridine (from Step C), 117 mg (1.0 mmol) of zinc cyanide, 20.1 mg (0.22 mmol) of tris(dibenzylideneacetone)dipalladium(0) and 48.7 mg (0.088) mmol of 1,1′-bis(diphenylphosphino)ferrocene in 2 mL of N-methylpyrrolidinone under argon was stirred at 100° C. for 1 h. The mixture was cooled and partitioned between ether and water. The organic layer was dried and concentrated. Chromatography on a Biotage 40S cartridge using 9:1 v/v hexanes/ether then 17:3 v/v hexanes/ether as the eluant afforded 87 mg of the title compound: ESI-MS (m/z) 258.2; HPLC A: 3.04 min.
