2-(Benzenesulfonyl)-3-phenyloxaziridine → HCID 178509395, compound

Participants

Reaction Steps

A mixture of 6-cyano-3-(4-piperidin-1-ylmethyl-phenyl)-9H-dipyrido[2,3-b;4′,3′-d]pyrrole (110 mg, 0.30 mmol) and 3-phenyl-2-(phenylsulfonyl)oxaziridine (102 mg, 0.39 mmol) in DCM (5.8 mL) was stirred at room temperature for 2 h. The solid was collected by filtration and washed with DCM (3×20 mL) to afford a bright yellow solid (100 mg, 90%). NMR (400 MHz, DMSO-D6): 8.98 (s, 1H), 8.91 (s, 1H), 8.90 (s, 1H), 8.83 (s, 1H), 7.66 (m, 4H), 4.43 (s, 2H), 3.13 (m, 2H), 2.14 (m, 2H), 1.59 (m, 4H), 1.34 (m, 2H). LCMS (method D): RT=8.82 min, M+H+=384.
