Procedure

To 5-(L-alaninyl)-amino-7-methyl-5,7-dihydro-6H-dibenz[b,d]azepin-6-one hydrochloride (Example 7B) (0.1500 g, 0.434 mmol) in THF (4 ml) was added pyridine (0.088 ml, 1.09 mmol) and 3-fluorobenzenesulfonyl chloride (Fluorochem Limited) (0.0928 ml, 0.477 mmol), stirred at RT overnight. The reaction mixture was evaporated to dryness. Water was added, filtered. The solid was purified with flash chromatography (silica, 6% MeOH/CH2Cl2, crystallized with CH2Cl2/hexane and washed with Et2O/hexane (1:1, v/v) to give the title compound (0.0580 g, 29%) as a white solid.
