5-Pyrimidinecarboxamide, 4-amino-2-(ethylthio)-N-methoxy-N-methyl- → (4-Amino-2-ethylsulfanyl-pyrimidin-5-yl)-(4-chloro-5-fluoro-2-methoxy-phenyl)-methanone

Participants

Reaction Steps

To a solution of 5-chloro-4-fluoro-2-iodoanisole (1.0 g, Example 375) was added isopropylmagnesium chloride (1.92 mL, 2M in tetrahydrofuran, Aldrich) and the reaction was stirred at −40 to −35° C. for 40 minutes before 4-amino-2-ethylsulfanyl-pyrimidine-5-carboxylic acid methoxy-methyl-amide (170 mg, Example 1) in tetrahydrofuran (4 mL) was added. The resulting reaction was quenched with aqueous ammonium chloride. Work-up and purification as in Example 47 gave (4-amino-2-ethylsulfanyl-pyrimidin-5-yl)-(4-chloro-5-fluoro-2-methoxy-phenyl)-methanone. MS (M+H)+, 342.
