To 1-(2-fluorobenzyl)-5-(thiazol-2-yl)-1H-1,2,4-triazole-3-carboximidamide (Intermediate-6, 0.33 mmol) was added a stock solution of 3-ethoxyacrylonitrile (3 equiv) and DBU (1 equiv) in pyridine (3 mL). The reaction was warmed to 110° C. and stirred for 46 h. The reaction mixture was conc. and purified using SiO2 chromatography and an appropriate gradient (CH3CN/MeOH/CH2Cl2) to afford 2-(1-(2-fluorobenzyl)-5-(thiazol-2-yl)-1H-1,2,4-triazol-3-yl)pyrimidin-4-amine (I-48) as a light tan solid (78% yield).
