Reaction Steps

A solution of 3-(3-(2-(2-(2-aminoethoxy)phenyl)propan-2-ylamino)-2-oxopyrazin-1(2H)-yl)-N-cyclopropyl-5-fluoro-4-methylbenzamide (Example 311, 0.17 g) dissolved in THF (10 mL) was treated with triethylamine (0.049 mL) and methyl bromoacetate (0.034 mL) under nitrogen. The resulting mixture was stirred at 20° C. for 16 h. The reaction mixture was diluted with 2M aqueous NaOH (2 mL) and methanol (2 mL). The solution was stirred at room temperature for 1 h, acidified with acetic acid and extracted with ethyl acetate (50 mL).
