Reaction Steps

A suspension of 2-((3-(azetidin-3-yl)-2-chloro-5-cyanophenyl)amino)-4-(ethylamino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (Example 367)(16 mg, 0.041 mmol) and (S)-(−)-propylene oxide (0.085 mL, 1.22 mmol) in a mixture of NMP (0.8 mL) and MeOH (0.2 mL) was stirred at 50° C. for 4.5 hr. The solvent was removed and the product was purified by preparative HPLC (Waters XBridge C18, 19×200 mm, 5-μm particles; Mobile Phase A: water with 20-mM ammonium acetate; Mobile Phase B: 95:5 acetonitrile: water with 20-mM ammonium acetate; Gradient: 15-55% B over 20 minutes, then a 5-minute hold at 100% B; Flow: 20 mL/min) to give the title compound (6.1 mg). This was converted to the mono HCl salt.
