Procedure

To a solution of 254 mg (0.7 mmol) 2-chloro-N-[(3-fluorophenyl)-methyl]-4-methyl-6-morpholin-4-yl-pyridine-3-carboxylic acid amide (synthesis is described in section a) of example 9) in MeCN (0.5 ml) were added 115 μl (1.4 mmol) pyrrolidine and 290 μl (2.1 mmol) NEt3. The RM was heated in the microwave to 120° C. for 30 min and subsequently to 140° C. for 45 min. Then the mixture was filtered through celite and concentrated in vacuo. Purification of the residue by CC (hexane/EtOAc 2:1), followed by crystallization (hexane/EtOAc) provided 164 mg (0.41 mmol, 59%) N-[(3-Fluorophenyl)-methyl]-4-methyl-6-morpholin-4-yl-2-pyrrolidin-1-yl-pyridine-3-carboxylic acid amide (example 24). [M+H]+ 399.2.
