A solution of 4-chloro-3-[3-({1-[2-(2-chloroethoxy)phenyl]-1-methylethyl}amino)-2-oxopyrazin-1(2H)-yl]-N-cyclopropylbenzamide (Example 3301, 0.22 g) dissolved in acetonitrile (3 mL) was treated with 40% aqueous methylamine (0.380 mL). The resulting mixture was stirred at 100° C. for 16 h in a sealed tube. The reaction mixture was filtered and purified by preparative HPLC (Phenominex Gemini column using a 95-5% gradient of aqueous 0.2% ammonia in acetonitrile as eluent). The fractions containing the desired compound were evaporated to afford the title compound (0.087 g).
