Procedure

According to the procedure of Example 62, 1-(4-chlorobenzoyl)-N-hydroxy-5-methoxy-2-methyl-1H-indole-3-methanamine is reacted with 1.1 eq of methyl isocyanate in dioxane/water (2:1) in the absence of sodium acetate. The crude product is purified by column chromatography (silica gel) eluting with a gradient of acetone/hexane to give pure 1-(4-chlorobenzoyl)-N-hydroxy-5-methoxy-2-methyl-N-[(methylamino)carbonyl]-1H-indole-3-methanamine (51%) as an amorphous solid.
