3-(Trifluoromethyl)benzoyl chloride → HCID 59860299, compound

Participants

Reaction Steps

To a solution of 4-chloro-11-oxa-7,10-diaza-benzo[b]fluoren-1-ylamine (35 mg, 0.13 mmol) in the dichloromethane (2.0 mL) is added 3-(trifluoromethyl)benzoyl chloride (54.2 mg, 0.26 mmol). After the mixture is stirred for 24 hours at room temperature, it is diluted with EtOAc and washed with saturated K2CO3, brine and water. The organic layer is dried, filtered and concentrated to give crude product, which is purified by flash silica gel column eluting with CH2Cl2 (100%) gradient to CH2Cl2/MeOH (98/2) to give the product as a solid: 1H NMR 400 MHz (DMSO) δ 10.85 (s, 1H), 9.53 (s, 1H), 9.37 (s, 1H), 8.63 (d, 1H), 8.24 (s, 1H), 8.19 (d, 1H), 7.87 (d, 1H), 7.77 (d, 1H), 7.72 (d, 1H), 7.67 (t, 1H), 7.48 (d, 1H); MS m/z 442.85 (M+1).
