Procedure

2-((3-(4-aminopiperidin-1-yl)-2-chloro-5-cyanophenyl)amino)-4-(ethylamino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (Example 329) (40 mg, 0.092 mmol) was mixed with N,N-diisopropylethylamine (0.2 ml, 1.145 mmol) in MeOH (1 ml) and THF (1 ml). methyl carbonochloridate (0.05 ml, 0.646 mmol) was added. The mixture was stirred at room temperature for 1 hr. LC/MS showed product formation. The white precipitate was formed and collected by filtration, washed with cold MeOH (15 ml), then water (5 ml) and dried with air-suction to give 31.7 mg of desired product.
