Versuchsvorschrift

A mixture of 2-(inden-1-yl)ethanol (CXVI-B, EXAMPLE 86, 0.8 g, 5 mmol), dimethylaminopyridine (0.02 g, 0.2 mmol) and triethylamine (1.7 ml, 12.5 mmol) in tetrahydrofuran (10 ml) is cooled to 0° and methanesulfonyl chloride (0.43 ml, 5.5 mmol) is added dropwise. After 45 min, 4-(piperazinyl)benzenecarboxamide (LXV, 1.23 g, 6 mmol), diisopropylethylamine (1.0 ml, 6 mmol) and ethyleneglycol (10 ml) are added and heated at 85° for 60 hr. The mixture is diluted with water and extracted with methylene chloride. The organic phase is separated, washed with saline, dried (magnesium sulfate), filtered and concentrated. Crystallization from ethyl acetate gives the title compound, mp 207°; NMR (CDCl3, TMS) 7.75-6.90, 6.28 and 3.39-2.68 δ.
