Reaction Steps
0.32 g of BOP, 0.08 g of pyrazinecarboxylic acid and then 0.37 mL of DIPEA are added, at a temperature of 0° C., to a solution of 0.25 g of the compound prepared in step 1.2 in 3 mL of acetonitrile. The medium is stirred at room temperature for 12 hours and then concentrated. The medium is taken up in EtOAc and washed 3 times with 10% Na2CO3 solution and then with saturated NaCl solution. After drying over MgSO4, the solution is concentrated and then purified by flash chromatography to give 0.23 g of a dark yellow solid.
