Procedure

2-(2-(2-(4-butyl-4-(dimethylamino)-1-(3-methyl-1H-indol-2-yl)cyclohexyl)-1H-indol-3-yl)ethyl)isoindolin-1,3-dione (450 mg, 0.749 mmol) and hydrazine monohydrate (2 ml, 41.2 mmol) were dissolved in methanol (20 ml) and then boiled with reflux for 45 min. For work up the batch was diluted with 1N NaOH (50 ml) and extracted with diethyl ether (3×20 ml). The combined organic phases were dried over Na2SO4 and then concentrated until dry. The product was obtained as a light beige-coloured solid with a yield of 302 mg (86%, melting point 105-112° C.). According to the NMR spectrum it was a mixture of the two possible diastereoisomers in a ratio of approx. 30:70.
