Procedure
The title compound was prepared as described in Example 215, starting from 1-(tert-butyl-dimethyl-silanyl)-7-chloro-1H-indole (prepared by TBDMS protection of 7-chloro-1H-indole using standard procedures) and (4-chloro-pyrimidin-2-yl)-(2,2,6,6-tetramethyl-piperidin-4-yl)-amine, followed by in situ cleavage of the TBDMS protecting group with catalytic amounts of TBAF. Yield: 280 mg (34%).
