m-Chloroperbenzoic acid → HCID 59519015, compound

Participants

Reaction Steps

3-Chloroperoxybenzoic acid (19 mg, 0.078 mmol) was added to a stirred solution of 2-[2-(3-chloro-4-fluorophenyl)-6-(4-isopropylperhydro-1,4-diazepin-1-yl)-4-oxo-4H-quinazolin-3-yl]-N-isopropylacetamide (EXAMPLE 6k) (40 mg, 0.078 mmol) in DCM (5 mL). The reaction mixture was stirred for 10 min at room temperature. The reaction mixture was diluted with DCM (10 mL) and washed with aqueous sodium bicarbonate solution (10 mL). The organic phase was dried (Na2SO4), concentrated under reduced pressure and purified by chromatography on silica gel with a gradient of DCM to DCM:MeOH (4:1, v/v) as eluent to afford 4-(2-(3-chloro-4-fluorophenyl)-3-(2-(isopropylamino)-2-oxoethyl)-4-oxo-3,4-dihydroquinazolin-6-yl)-1-isopropyl-1,4-diazepane 1-oxide (EXAMPLE 12a) (25 mg, 0.047 mmol, 61%).
