Participants

Reaction Steps

To 5-(L-alaninyl)-amino-7-methyl-5,7-dihydro-6H-dibenz[b,d]azepin-6-one (Example 7B) (0.1500 g, 0.0485 mmol) in DMF (4 ml) were added pyridine (0.059 ml, 0.728 mmol) and 1-octanesulfonyl chloride (Aldrich) (0.095 ml, 0.485 mmol), stirred at RT overnight. The reaction mixture was evaporated to dryness. Water was added, extracted with EtOAc, washed with brine, dried over MgSO4. Evaporation and flash chromatography (silica, 5% MeOH/CH2Cl2), gave the title compound (0.0805 g, 34%) as a yellow solid.
