Reaction Steps

To a solution of 8-chloro-3-methyl-2,5-dioxo-2,3,4,5-tetrahydro-1H-benzo[b]azepine-4-carboxylic acid methyl ester (iii-i) (0.2 g, 0.7 mmol) in DMF (2 mL) was added H2O (0.3 mL) and the reaction mixture heated to 230° C. in a microwave reactor for 5 minutes. H2O (20 mL) was added to the reaction mixture and the resulting precipitate was filtered and washed with H2O. The solid was dried under reduced pressure at 40° C. for 16 h to afford iv-i (0.12 g, 77%) as a white solid: MS m/z═224 (M+H).
