Procedure

A solution of 5-(5-amino-2-chloro-pyridin-3-yl)-5-fluoromethyl-morpholine-3-thione (33 mg, 0.12 mmol), 5-bromo-pyridine-2-carboxylic acid (36 mg, 0.18 mmol) and HOAt (29 mg, 0.215 mmol) in DMF (0.4 ml) was cooled to 0° C. and DIPEA (0.042 ml, 0.24 mmol) and EDC (34 mg, 0.18 mmol) were added, the reaction mixture was stirred at 0° C. for 10 min, then allowed to warm to room temperature over night. At 0° C. aq. 1M KHCO3 was added and the mixture extracted with toluene. The combined organic layers were washed with water, dried with Na2SO4 and evaporated. The residue was taken up in DCM/MeOH 65/35 from which the product started to crystallize. Filtration, rinsing of the crystallized material with DCM and drying provide the title compound as yellow crystals.
