Reaction Conditions

Reaction Steps

C-(5′-isopropyl-2′-methoxy-4-trifluoromethyl-biphenyl-2-yl)-methylamine (3.47 g) is dissolved in dioxane (50 ml), and thereto are added 5-bromo-2-chloropyrimidine (5.30 g) and N,N-diisopropylethylamine (5.74 ml) and the mixture is stirred at 100° C. for 2 hours and a half. The reaction solution is allowed to cool to room temperature, and concentrated under reduced pressure. The resulting residue is purified by silica gel column chromatography (hexane:ethyl acetate=50:1→22:3) to give (5-bromo-pyrimidin-2-yl)-(5′-isopropyl-2′-methoxy-4-trifluoromethyl-biphenyl-2-ylmethyl)-amine (4.82 g). MS (m/z): 482/480 [M+H]+
