Reaction Steps

A mixture of 4-(4-chloro-3-(trifluoromethoxy)phenoxy)phenethyl carbamimidate (80 mg, 0.213 mmol), (Z)-methyl 3-hydroxy-2-(pyrimidin-5-ylmethyl)acrylate (124 mg, 0.640 mmol) and Cs2CO3 (174 mg, 0.534 mmol) in 1,4-dioxane (2 mL) was heated with a microwave condition at 110° C. for 2 h. After cooling, the mixture was filtered through the celite. The filtrate was concentrated and purified via reverse phase flash chromatography to afford the title compound (48 mg, 0.093 mmol, 43.3% yield). LCMS: rt=3.48 min, [M+H+]=519
