To a solution of 6-(3-methyl-5-pyridin-2-yl-3H-[1,2,3]triazol-4-ylmethoxy)-nicotinic acid (76 mg, 0.24 mmol) and TBTU (86 mg, 0.27 mmol) in DMF (1.2 mL) was added DIPEA (209 μL, 1.22 mmol). Then 4-aminotetrahydropyran (27 mg, 0.27 mmol) was added and the mixture was stirred at room temperature under Ar for 1 h. The mixture was then evaporated and purification by chromatography (silica, 50 to 100% ethyl acetate in heptane) afforded the title compound (67 mg, 70%) as a white solid after recrystallisation from methanol/water. MS: m/e=395.1 [M+H]+.
