Procedure

To a solution of 2.0 gm (5.74 mMol) 5-amino-3-(1-methylpiperidin-4-yl)-1H-indole dihydrochloride mono-ethanolate and 5.0 mL (36 mMol) triethylamine in 100 mL dichloromethane were added 0.74 mL (12.6 mMol) methyl isocyanate. The reaction mixture was stirred for 15 minutes and was then washed with 100 mL of water. The remaining organics were dried over sodium sulfate and concentrated under reduced pressure. The resultant residue was crystallized from acetonitrile to give 1.05 gm (64%) of the title compound.
