実験手順
5-Cyclopropyl-6-cyclopropylmethoxy-pyrazine-2-carboxylic acid (Example 10 g, 100 mg, 0.43 mmol) was suspended in DMF (3 mL). TBTU (224.14 mg, 0.85 mmol), DIEA (0.31 mL, 2.24 mmol) and (αS)-α-amino-benzeneacetamide (CAN 6485-52-5, 51.2 mg, 0.51 mmol) were added and the reaction mixture was stirred at room temperature for 12 hours. The mixture was extracted with ethyl acetate and water; the organic phase was dried over Na2SO4, filtered and concentrated in vacuo. The crude material was purified by reverse phase preparative HPLC (Xbridge-C18, 5 μ, 19×250 mm/acetonitrile/0.1% ammonia in water) to give the desired product (15 mg, 9.58%) as white solid; LC-MS (UV peak area, ESI) 93.20%, 367.4 (M+H).
