The title compound was synthesized in the manner essentially the same as the Example 1 by condensing 4-(tert-butyl-diphenyl-silanyloxy)-1-(2-oxo-ethyl)-cyclohexanecarboxylic acid methyl ester (Intermediate 8) with 4-[(S)-3-(2-methyl-pyrrolidin-1-yl)-cyclopentyl]-phenylamine (Intermediate 15), and subsequently cyclization, followed by de-protection with TBAF in THF at 60° C. for 5 h.
