Versuchsvorschrift

A mixture of 4-(1,4-dihydroindeno[1,2-c]pyrazol-3-yl)phenol (0.76 g, Example 30) 4-(2-hydroxyethyl)morpholine (0.85 g), triphenylphosphine (1.77 g) and dichloromethane (20 ml) were stirred together with ice/water bath cooling and diethylazodicarboxylate (1.16 g) was added dropwise. The resultant mixture was allowed to warm to room temperature and stirred for about 24 hours. The solvent was evaporated off under reduced pressure and the residue purified by flash column chromatography on silica using ethyl acetate/ethanol (25%) to give a solid. The solid was triturated with diethyl ether (10 ml) and the solid filtered, washed with diether and dried at about 65° C. to give 3-[4-(2-morpholinoethoxy)phenyl]-1,4-dihydroindeno[1,2-c]pyrazole, m.p. 175-6° C.
