Reaction Steps

This compound was prepared according to General Method 16 (EXAMPLE 30) from (±)-2,3-dihydro-2-(hydroxymethyl)-7-isopropoxy-1-(2,2,2-trifluoroethyl)-9-(trifluoromethyl)-1H-[1,4]oxazino[3,2-g]quinoline (EXAMPLE 28) (11 mg, 0.026 mmol), NaH (5.0 mg, 0.12 mmol) and 1-iodopropane (21 mg, 0.12 mmol) in 1.0 mL THF to afford 6 mg (50%) of (±)-2,3-dihydro-7-isopropoxy-2-(1-propoxymethyl)-1-(2,2,2-trifluoroethyl)-9-(trifluoromethyl)-1H-[1,4]oxazino[3,2-g]quinoline, a yellow oil, after flash chromatography (5:1 hexanes:EtOAc).
