Product 1

HCID 118451458(S)-1-[6-Cyclopropylmethoxy-5-(3,3-difluoro-azetidin-1-yl)-pyridine-2-carbonyl]-4,4-difluoro-pyrrolidine-2-carboxylic acid amide

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 (S)-4,4-difluoropyrrolidine-2-carboxamide hydrochloride (426844-51-1) in the presence of TBTU and DIEA to obtain the title compound as colorless oil; MS (EI): m/e=417.5 [MH+].
