PROCEDURE

实验过程

Sodium azide (78 mg, 1.2 mmol) and ammonium chloride (21 mg, 0.40 mmol) were added to a solution of 4-cyanomethyl-8-fluoro-3-oxo-3,4-dihydro-2H-quinoxaline-1-carboxylic acid 2-methyl-4-(2,3,4,5-tetrahydrobenzo[b]azepine-1-carbonyl)benzylamide from Example 13 (210 mg, 0.40 mmol) in DMF (5 ml) and the mixture was stirred at 100° C. for 18 h. The mixture was cooled and evaporated in vacuo. The residue was purified by flash chromatography on silica (eluant CHCl3 100% to CHCl3:methanol;triethylamine 97:2:1 to CHCl3:methanol;triethylamine 94:4:2). The product was partitioned between chloroform and potassium hydrogen sulphate, separated and the organic phase was dried and evaporated in vacuo; yield 33 mg, 15%.
