Procedure
Pyrrolidine-2-carboxylic acid [6-(2-phenylchroman-6-yloxy)pyridin-3-yl]amide and its derivatives were prepared as described for piperidine-4-carboxylic acid [6-(2-phenylchroman-6-yloxy)pyridine-3-yl]amine in Example 19 a) and b) but replacing N-(tert-butoxycarbonyl)isonipecotic acid with (S),(R) or (R,S)-pyrrolidine-1,2-dicarboxylic acid 1-tert-butyl ester and 5-amino-2-(2-phenylchroman-6-yloxy)-pyridine by an appropriate 5-aminopyridine derivatives.
