Reaction Steps
A solution of 3-chlorobenyl alcohol (9.57 g, 67.1 mmol) in toluene (134 ml) at 23° C. under a nitrogen atmosphere was treated with NaH (60% dispersion in oil, 2.5 g, 67.1 mmol). The resulting suspension was heated to reflux for 30 min and cooled to room temperature. The mixture was treated with 2,6-dichloropyrazine (10.0 g, 67.1 mmol) and heated to reflux for 18 h. The reaction mixture was cooled to room temperature and partitioned between water and EtOAc. The organic phase was washed with brine, dried over MgSO4 (anhydrous), filtered and concentrated in vacuo. The residue was purified by flash chromatography (CH2Cl2-hexanes 3:7) to afford 10.0 g of the title compound (I-3l) as a clear oil (58%).
