Diisopropylethylamine → trans-N-(7-chloro-2,3,4,14b-tetrahydro-1H-dibenzo[b,f]pyrido[1,2-d][1,4]oxazepin-1-yl)-4-phenylbenzamide

Participants

Reaction Steps

DIPEA (18.6 μL, 0.14 mmol) and 4-phenylbenzoyl chloride (15.2 mg, 0.07 mmol) were added to a solution of trans-7-chloro-2,3,4,14b-tetrahydro-1H-dibenzo[b,f]pyrido[1,2-d][1,4]oxazepine-1-amine maleate (9.6 mg, 0.02 mmol) in 1 mL of CH2Cl2. The resulting mixture was stirred for 18 h at room temperature. The organic layer was washed with 5% aqueous sodium bicarbonate and H2O, dried (Na2SO4) and evaporated. Additional chromatography on silica (elution with toluene/ethyl acetate 9:1→toluene/ethyl acetate 1:1) gave trans-N-(7-chloro-2,3,4,14b-tetrahydro-1H-dibenzo[b,f]pyrido[1,2-d][1,4]oxazepin-1-yl)-4-phenylbenzamide (4.6 mg, 44%). Data: (m/z)=350 (M+H)+.
