Procedure: To solution of 2-((2-chloro-5-cyano-3-(2-oxopiperazin-1-yl)phenyl)amino)-4-(cyclopropylamino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (Example 628)(20 mg, 0.045 mmol) in DMF (0.5 mL) was added 2-bromo-N-methylacetamide (13.54 mg, 0.089 mmol) followed by K2CO3 (73.9 mg, 0.535 mmol) at room temperature and stirred at room temperature for 1 h, LC-MS indicated completion. Purification via preparative HPLC gave the title compound as a yellow solid (5.9 mg). Purification via preparative HPLC

Procedure: Sodium hydride (60% in oil, 0.010 g, 0.25 mmol) is added to a solution of [2-(2,6-difluorophenoxy)-9-ethyl-9H-purin-8-yl]-(2-chlorophenyl)-amine, 14, (0.1 g, 0.25 mmol) in THF (3 mL). After 5 minutes at room temperature 2-bromo-N-methyl-acetamide (0.06 mL, 0.37 mmol) is added and stirring is continued for 1 hour. The mixture is diluted with H2O (25 mL) and extracted three times with EtOAc (50 mL). The combined organic layers are washed with brine, dried over MgSO4, concentrated in vacuo and the residue purified by HPLC to afford 45 mg (38% yield) of the desired product as a yellow solid. 1H NMR (300 MHz, CDCl3) δ 8.54 (s, 1H), 7.54-7.59 (m, 2H), 7.15-7.36 (m, 4H), 7.04 (t, J=7.8 Hz, 2H), 4.53 (s, 2H), 3.61 (q, J=7.2 Hz, 2H), 2.85 (d, J=4.8 Hz, 3H), 0.99 (t, J=7.2 Hz, 3H); ESI/MS: 473 (M+H). extracted three times with EtOAc (50 mL) The combined organic layers are washed with brine dried over MgSO4 concentrated in vacuo the residue purified by HPLC

Procedure: At room temperature (RT), 53.6 mg (0.2 mmol) of 2-amino-4-(4-hydroxyphenyl)-6-sulfanyl-3,5-pyridinedicarbonitrile and 45.6 mg (0.3 mmol) of N-methylbromoacetamide are stirred in 0.5 ml of dimethylformamide (DMF) together with 33.6 mg (0.4 mmol) of NaHCO3 for 4 hours. Thin-layer chromatography (TLC) (CH2Cl2/CH3OH 10:1) shows complete conversion. The entire mixture is diluted with water and ethyl acetate (EA) and the EA phase is dried with MgSO4 and concentrated under reduced pressure. The residue crystallizes from methanol. the EA phase is dried with MgSO4 concentrated under reduced pressure The residue crystallizes from methanol
