A solution of 249 mg (0.81 mmol) 2-(ethyl(methyl)amino)-4-methyl-6-morpholino-pyridine-3-carboxylic acid ethylester and 924 μl (8.1 mmol) 4-fluoro-benzylamine in toluene (17 ml) was treated with 2.85 ml (2M in toluene, 5.7 mmol) AlMe3 and was subsequently heated to 120° C. for 4 d. Then the solution was diluted with water, a 1M aq. NaOH sol. and EtOAc. The organic layer was separated, washed with a 2M aq. NaOH sol. and brine, dried over MgSO4 and concentrated in vacuo. Purification of the residue by CC (hexane/EtOAc 3:1) provided 127 mg (0.33 mmol, 40%) 2-(Ethyl-methyl-amino)-N-[(4-fluorophenyl)-methyl]-4-methyl-6-morpholin-4-yl-pyridine-3-carboxylic acid amide (example 174).
