実験手順

A mixture of 6.0 g (19.2 mmol) 2,6-dichloro-N-(4-fluorobenzyl)-4-methyl-pyridine-3-carboxylic amide (synthesized according to the methods described in section a) of example 2), 3.9 g (28.7 mmol) (R)-3-methylmorpholine hydrochloride, 13.0 ml (76.6 mmol) and NMP (18.4 ml) was heated in the MW to 180° C. for 16 h. After cooling to RT the mixture was partiotionated between EtOAc and a 2M aq. NaOH sol. The organic layer was separated, dried over MgSO4 and concentrated in vacuo. Purification of the residue by CC (hexane/EtOAc 1:1) provided 1.4 g (3.7 mmol, 20%) 2-chloro-N-(4-fluorobenzyl)-4-methyl-6-[(3R)-3-methylmorpholino]-pyridine-3-carboxylic amide.
