55% Stage #1: N,N-dimethyl-formamide With trichlorophosphate at 0 - 5℃; for 1h; Stage #2: N1-(4-Fluorophenyl)acetamide at 0 - 80℃; Inert atmosphere; 1.1 General procedure for synthesis of 2-chloroquinoline-3-carbaldehydes (13-18) General procedure: A round bottom flask charged with N, N-dimethylformamide (7.0 mol) was placed on an ice bath and the temperature kept at 0-5 °C. To this flask, phosphorus oxychloride (12.0 mol) was added dropwise and the reaction mixture was stirred for 1 h at 0-5 °C. The appropriate N-phenylacetamide (1.0 mol) was then added and stirred for a further 30 min followed by heating under reflux for 5-4 h under N2 atmosphere. After the reaction was completed (TLC monitoring), the mixture was poured into 200 g of crushed ice under constant stirring. The precipitate obtained was vacuum filtered, washed with water (2 × 30 mL), air-dried and recrystallised from EtOAc to give the relevant compounds in 36-84% yields.
