Reaction Steps

A solution of N-cyclopropyl-3-fluoro-5-[3-({1-[2-(3-hydroxypropyl)phenyl]-1-methylethyl}amino)-2-oxopyrazin-1(2H)-yl]-4-methylbenzamide (Example 323h) (0.4 g) dissolved in THF (10 mL) was treated with carbon tetrabromide (0.277 g) under nitrogen. The resulting mixture was cooled to 0° C. before adding triphenylphosphine (0.219 g). The reaction mixture was stirred at room temperature for 16 h. The reaction mixture was evaporated and the residue purified (SiO2 chromatography eluting with 50% DCM in ethyl acetate) to give the subtitle compound as a solid (0.135 g).
