Dissolve 3-(1-ethyl-5-fluoro-indan-1-yl)-1-methyl-1H-indol-7-ylamine (0.18 g, 0.58 mmol) in pyridine (3 ml). Add methanesulfonyl chloride (0.05 ml, 0.70 mmol, 1.20 equivalents) and stir at room temperature under nitrogen overnight. Dilute with ether, wash with 1N aqueous hydrochloric acid (2×), dry over anhydrous sodium sulfate, filter, and concentrate solution in vacuo. Purify the residue on silica eluting with 0 to 100% ethyl acetate/hexanes over 25 minutes to provide the title compound as a white solid (0.19 g, 86%). LC-MS m/z 387.1 (M++1).
