HCID 118451453((1S,4S)-5-Benzyl-2,5-diaza-bicyclo[2.2.1]hept-2-yl)-[6-cyclopropylmethoxy-5-(3,3-difluoro-azetidin-1-yl)-pyridin-2-yl]-methanone

Procedure

In analogy to the procedure described in Example 47 b), 6-cyclopropylmethoxy-5-(3,3-difluoro-azetidin-1-yl)-pyridine-2-carboxylic acid (Example 1 b)) was reacted with (1S,4S)-2-benzyl-2,5-diazabicyclo[2.2.1]heptane dihydrobromide (116258-17-4) in the presence of TBTU and DIEA to obtain the title compound as colorless oil; MS (EI): m/e=455.7 [MH+].
