Reaction Steps

3chloro-N-[5-(2-chlorophenyl)-1-(2,6-dichlorophenyl)-3-(4-methoxybenzyl)-2-oxo-1,2,3,4-tetrahydroquinazolin-7-yl]propane-1-sulfonamide (93 mg, 0.14 mmol) in morpholine (0.25 mL) was heated at 130° C. for 45 min. The reaction mixture was cooled to rt, diluted with ethyl acetate, washed with water, dried (Na2SO4), and concentrated under reduced pressure. The product was purified by flash chromatography on a Biotage 40S column, eluting with 60:40 hexanes-acetone to yield N-[5-(2-chlorophenyl)-1-(2,6-dichlorophenyl)-3-(4-methoxybenzyl)-2-oxo-1,2,3,4-tetrahydroquinazolin-7-yl]-3-morpholin-4-ylpropane-1-sulfonamide. Mass spectrum (ESI) 729 (M+1).
