Procedure

3-[3-[[1-[2-(2-chloroethoxy)phenyl]cyclopropyl]amino]-2-oxo-1(2H)-pyrazinyl]-N-cyclopropyl-5-fluoro-4-methyl-benzamide (Example 259d, 5 g) and ethanolamine (6.1 mL) were heated at 100° C. in dioxane (20 mL) in a sealed tube for 16 h. Purification of the cooled solution by preparative HPLC (Xterra column, eluting with a gradient of acetonitrile in 0.2% (v/v) aqueous ammonia) gave the title product (2.95 g) after solvent removal in vacuo and trituration with isohexane/diethyl ether (1:1 80 mL).
