At 0° C., 50 mg (0.107 mmol) of 2-amino-6-([2-(4-chlorophenyl)-1,3-thiazol-4-yl]methylsulfanyl)-4-(1,3-thiazol-5-yl)pyridine-3,5-dicarbonitrile were dissolved in 1.5 ml of concentrated hydrochloric acid, and 22 mg (0.321 mmol) of sodium nitrite were added. The mixture was stirred initially at 0° C. for one hour and then at room temperature overnight. Purification of the reaction mixture was by preparative HPLC (acetonitrile/water: 10:90→95:5, 0.1% TFA added). This gave 9 mg (17% of theory) of the target compound.
