Versuchsvorschrift

6-Chloropyridine-3-carboxylic acid (Ig, 6.35 mmol) and thionyl chloride (10 mL, 138 mmol) were heated to reflux for 2 hours. The mixture was concentrated under vacuum and the residue was azeotroped with diethyl ether and evaporated. A portion of this acid chloride (0.75 g, 4.26 mmol) was then added to a solution of 4-amino-N-hydroxy-6-[methyl(phenyl)amino]-1,3,5-triazine-2-carboximidamide (prepared in an analogous manner to Intermediate 1, 0.920 g, 3.55 mmol) in pyridine (12 mL) and the mixture was stirred at room temperature overnight before being heated to 70 C for 3 h. The mixture was cooled to room temperature and concentrated under vacuum. Water was added and the mixture was stirred for 30 min. The solids were filtered and washed with further water. The solid was then azeotroped with toluene and dried under vacuum to afford the title compound, which was used without purification in the next step. Method B HPLC-MS: MH+ requires m/z=381 Found: m/z=381, Rt=1.99 min (35%).
