Procedure

A solution of [(4,6-dimethyl-1H-indol-3-yl)methyl]dimethylamine from Step A (98.0 mg, 0.484 mmol) and potassium cyanide (315 mg, 4.84 mmol) in DMF (2 mL) and H2O (2 mL) was heated at 100° C. for 2 h. The reaction mixture was partitioned between EtOAc (20 mL) and saturated NaCl (10 mL). The layers were separated and the organic layer was dried over Na2SO4, filtered, and concentrated in vacuo. Purification of the crude product by silica gel chromatography, eluting with a gradient of CH2Cl2:MeOH-100:0 to 98:2, gave the title compound. MS: m/z=185 (M+1).
