Participants

Reaction Steps

To a solution of the acid 5-cyclopropyl-4-((3-methyloxetan-3-yl)methoxy)picolinic acid (20 mg, 76.0 μmol) in dichloromethane (1 ml) was added DIPEA (24.5 mg, 33.2 μl, 190 μmol) and 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholin-4-ium chloride (23.1 mg, 83.6 μmol). The reaction is stirred for 30 minutes at room temperature followed by addition of 2-(5-phenyl-1,3,4-oxadiazol-2-yl)propan-2-amine (CAN 68176-04-5, 15.4 mg, 76.0 μmol) and the reaction mixture was stirred overnight at room temperature. The reaction was diluted with dichloromethane (5 mL) and washed with a 0.2M aqueous solution of hydrochloric acid (3×10 mL) and brine (15 mL). The organic phase is dried over magnesium sulfate and evaporated down to dryness. The crude material was purified by flash chromatography on silica eluting with a gradient of heptane and ethyl acetate to yield the title compound (24.3 mg, 71%). MS (ESI, m/z): 449.7 (M+H+).
