실험 절차

330 mg (8.3 mmol, 60% w/w in mineral oil) NaH were slowly added to Methanol (30 ml) at RT and stirring was continued at RT for 45 min. Then 2.35 g (7.5 mmol) 2,6-dichloro-N-(3-fluorobenzyl)-4-methyl-pyridine-3-carboxylic acid amide (synthesis is described in section a) of example 2) were added and the RM was heated to 70° C. for 24 h. After cooling to RT water (10 ml) was added and most of the MeOH was removed in vacuo. The mixture was then extracted with EtOAc and the organic layer was washed twice with brine, dried over MgSO4 and concentrated in vacuo. Crystallisation (hexane/EtOAc 3:1) of the residue yielded 1.24 g (0.4 mmol, 54%) 6-Chloro-N-[(3-Fluorophenyl)-methyl]-2-methoxy-4-methyl-pyridine-3-carboxylic acid amide.
