Yield	Reaction Conditions	Operation in experiment
80%	With sodium carbonate;tetrakis(triphenylphosphine) palladium(0); In 1,2-dimethoxyethane; water; at 20℃; for 20h;Heating / reflux;	a) 2-[2Benzvloxv)-5-chlorol-3-chloro-pvrazine 2, 3-Dichloropyrazine (255mg, 1.71 mmol), 2- (benzyloxy)-5-chloro-phenylboronic acid (450mg, 1.71 mmol) and sodium carbonate (139mg) were stirred in DME (ethylene glycol dimethyl ether) -water (1: 1,10 mL) under nitrogen for 20 minutes, then tetrakis (triphenylphoshine) palladium (0) (100mg) was added and the mixture heated at reflux for 20 hours. Upon cooling, saturated ammonium chloride was added and the resultant mixture was extracted with DCM (x 2). The combined extracts were dried (MgS04), filtered and evaporated. The residue was chromatographed on silica gel with with cyclohexane containing ethyl acetate (5-100%) to yield the title compound (448mg, 80%). LC/MS Rt = 3.47 min, [MH+] 331.
