반응 단계
A mixture of 146.3 mg (0.45 mmol) (6-chloro-benzooxazol-2-yl)-(R)-1-pyrrolidin-3-ylmethyl-amine, hydrochloride (intermediate 1), 106.7 mg (0.586 mmol) 2,6-dimethoxy-benzoic acid (commercially available) and 206.9 mg (0.64 mmol) TBTU in 4 mL DMF and 0.3 mL DIPEA was shaken at room temperature over night. The mixture was acidified with formic acid and subjected to purification by preparative HPLC on reversed phase eluting with a gradient formed from acetonitrile, water and formic acid. The product containing fractions were evaporated to yield 72 mg (38%) of the title compound. MS (m/e): 416.2 (MH+).
