4-Fluoro-4-(4-fluoro-benzoyl)-piperidine-1-carboxylic acid tert-butyl ester (0.122 g, 0.375 mmol) was solved in dichloromethane (2 mL) and trifluoroacetic acid (0.258 mL, 3.37 mmol) was added at 0° C. Aqueous NaHCO3 is slowly added until pH 9 and the mixture extracted with 3 times with dichloromethane and ethyl acetate. The solvent was evaporated to yield g (0. mmol, 100%) of a white solid that was used without purification on the next steps. MS (m/e): 226.1 (M+H+).

Procedure:
A solution of 400 mg of 3-[8-[(t-butoxyformamido)methyl]-6,7,8,9-tetrahydropyrido[1,2-a]indol-10-yl]-4-(1-methyl-3-indolyl)furan-2,5-dione in 50 ml of dimethylformamide and 50 ml of water was treated with 2.5 g of hydroxylamine hydrochloride and 2.5 g of potassium carbonate and the solution obtained was heated to 100° C. The solvents were evaporated and the residue was dissolved in dichloromethane, washed with water and dried. The solvent was removed under reduced pressure and the residue was crystallized from ethyl acetate/petroleum ether to give 190 mg of 3-[8-[(t-butoxyformamido)methyl]-6,7,8,9-tetrahydropyrido[1,2-a]indol-10-yl]-1-hydroxy-4-(1-methyl-3-indolyl)pyrrole-2,5-dione of melting point 238°-240° C.

Procedure:
To a solution of 50 g of 5-bromo-2-hydroxy-3-methoxybenzaldehyde in 200 ml of an ethanol:THF=1:1 mixed solvent there was added 16.4 g of sodium borohydride while cooling on ice. After stirring at room temperature for 2 hours, 1N hydrochloric acid was added to the reaction mixture while cooling on ice. The organic layer was washed with ethyl acetate and dried over anhydrous magnesium sulfate. The desiccating agent was filtered off, and the filtrate was concentrated under reduced pressure to give the title compound (50 g) as a crude product.

Procedure:
A mixture of 1-chloro-3-(dimethylamino)-2-methylpropane hydrochloride (200 g), thiourea (97.3 g) and ethanol (950 ml) was stirred and heated under reflux for 72 hours. The solution was allowed to cool and the solvent was removed in vacuo. The residue was dissolved in a small volume of ethanol and ether was added until the first permanent opalescence was observed. The mixture was stored at 4° C. for 16 hours. The solvent was removed in yacuo to afford a waxy/oily solid which was dried in vacuo over calcium chloride for 48 hours, then triturated with propan-2-ol. The resulting solid was collected by filtration, washed with propan-2-ol, and dried in vacuo to give S-[3-(dimethylamino)-2-methylpropyl]isothiourea dihydrochloride as a pale brown solid (90 g).
