Reaction Steps

Following general procedure A-1, tert-butyl (trans-4-(2-(dimethylamino)ethyl)cyclohexyl) carbamate (336 mg, 1.24 mmol) was reacted with 6 N aqueous HCl (2 mL) to afford a viscous colorless oil. The oil was dissolved in dioxane (10 mL) and DMF (5 mL) followed by the addition of 1-(6-bromo-4-chloroquinolin-3-yl)ethanone (285 mg, 1.0 mmol), K2CO3 (0.55 g, 4.0 mmol), and N,N-diisopropylethylamine (1.0 mL, 5.8 mmol) and the resultant suspension was heated at 100° C. for 16 h. The reaction mixture was cooled to room temperature, diluted with satd. aq. NaHCO3 and extracted with ethyl acetate. The combined organic layers were dried over anhydrous sodium sulfate and concentrated. Purification by column chromatography (silica, 0-20% methanol/dichloromethane) afforded the desired product (227 mg, 54%) as a light yellow-brown solid. ESI MS m/z 418 [C21H28BrN3O+H]+
