Reaction Steps

To a solution of 2,3-dichloropyrazine (1.45 g, 9.73 mmol) and methyl tetrahydro-2H-pyran-4-carboxylate (2.60 mL, 19.47 mmol) in Toluene (19.47 mL) at room temperature was added LiHMDS (19.47 mL, 19.47 mmol, 1M solution) dropwise. After overnight room temperature stirring, reaction was quenched with saturated NH4Cl solution and extracted with EtOAc. Purification by Biotage (0-10% MeOH/DCM) produced product.
