Procedure
To a stirred solution of 4-(2-oxo-1,4-dihydro-2H-quinazolin-3-yl)-piperidine-1-carboxylic acid (8-hydroxy-2-methyl-3-oxo-2,3,4,5-tetrahydro-1H-benzo[c]azepin-4-yl)-amide (27 mg, 0.058 mmol) in dichloromethane (10 mL) was added methanol (2 mL), ether (3 mL) followed by sulfuryl chloride (70 μL) at room temperature. The reaction mixture was stirred for additional 12 h and then concentrated. The crude product was purified by Prep HPLC to give 4-(2-Oxo-1,4-dihydro-2H-quinazolin-3-yl)-piperidine-1-carboxylic acid (7,9-dichloro-8-hydroxy-2-methyl-3-oxo-2,3,4,5-tetrahydro-1H-benzo[c]azepin-4-yl)-amide in 58% yield. MS (ESI) 532 (M+H); Rf=1.40.
