반응 단계
In analogy to the procedure described in Example 47 b), 5-cyclopropyl-6-(tetrahydro-pyran-4-ylmethoxy)-pyridine-2-carboxylic acid (which can e.g. be prepared in a similar manner than 5-cyclopropyl-6-(tetrahydro-furan-2-ylmethoxy)-pyridine-2-carboxylic acid (Example 4 b)) was reacted with cyclopropyl-(5-methyl-[1,2,4]oxadiazol-3-yl)-methylamine (which can e.g. be prepared in a similar manner than (S)-2-cyclopropyl-1-(5-methyl-[1,2,4]oxadiazol-3-yl)-ethylamine (Example 32 e)) in the presence of TBTU and DIEA to obtain the title compound as colorless oil; MS (EI): m/e=413.1 [MH+].
