Procedure

A round bottom flask under nitrogen atmosphere was charged with (±)-trans-1-(2-methyl-4-phenylamino-3,4-dihydro-2H-quinolin-1-yl)-ethanone (0.110 g, 0.39 mmol, 1.0 equiv) and 2-furoyl chloride (0.193 mL, 1.9 mmol, 5.0 equ), pyridine (1.0 equ.) and dry toluene (5 mL). The solution was heated to 50° C. for 5 h. The reaction mixture was evaporated in vacuo. The residue was purified by Biotage flash system (30% hexane/70% ethyl acetate to 50% hexane/50% ethyl acetate) to yield the trans isomer 34% yield.
