Reaction Steps

Lithium hydroxide monohydrate (0.177 g) in water (5.00 mL) was added to methyl 3-[3-({1-[2-(2-chloroethoxy)phenyl]-1-methylethyl}amino)-2-oxopyrazin-1(2H)-yl]-5-fluoro-4-methylbenzoate (Example 316b, 1.17 g) in THF (10 mL) and the reaction mixture was stirred for 4 h at room temperature. Water was added and the solution acidified with 2M HCl. This was extracted into ethyl acetate (2×). The combined organics were dried (MgSO4), filtered and evaporated to afford the subtitle compound as a solid (1 g).
