실험 절차

A mixture of 11 mg (0.04 mmol) 6-cyclopropylmethoxy-5-piperidin-1-yl-pyrazine-2-carboxylic acid, 15.3 mg (0.048 mmol) TBTU, 15.3 mg (0.119 mmol) DIPEA and 7 mg (0.059 mmol) (S)-2-amino-4-methyl-pentan-1-ol (commercially available) in 1 mL DMF was shaken at room temperature for 16 h. The mixture was subjected to purification by preparative HPLC on reversed phase eluting with a gradient formed from acetonitrile, water and NEt3. The combined product fractions were evaporated to yield 10.5 mg (70%) of the title compound. m/z (ES+): 377.5 (M+H).
