Procedure:
8-Hydroxy-6,6-dimethyl-11-oxo-6,11-dihydro-5H-benzo[b]carbazole-3-carbonitrile (Compound A6, 50 mg, 0.165 mmol) was dissolved in DMF (1.5 mL), added with sodium hydride (13 mg, 2.0 eq.) and dimethylsulfamoyl chloride (0.02 mL, 1.2 eq.), and then stirred at room temperature for 1 hr. Water was added to the reaction solution, which was then extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over sodium sulfate. The drying agent was removed by filtration and the residues were concentrated under reduced pressure to obtain the target compound (yellowish white powder, 62 mg, 92%).

Procedure:
18 g (46.5 mM) of 8α-benzyloxycarbonylamino-6-cyanoergoline obtained from step (b) in 100 ml acetic acid are added to a suspension of 40 g zinc in 100 ml acetic acid. 40 ml water are added and the mixture is heated at 100° for 10 hours. To work up, the mixture is filtered through a filtering aid such as Hyflo and concentrated in a rotary evaporator. The residue is partitioned between potassium bicarbonate aqueous solution and methylene chloride/isopropanol (b 9:1). The organic phase is dried over sodium sulphate, filtered and concentrated to give the heading compound in crude form.

Procedure:
To a solution of (2S,4S)-2-(methanesulfonyloxy)methyl-1-(4-nitrobenzyloxycarbonyl)-4-(triphenylmethylthio)pyrrolidine (8.76 g) in dimethylformamide (80 ml) were added (2S)-2-(hydroxymethyl)pyrrolidine (8.72 g) and triethylamine (3.86 ml) and the mixture was stirred at 100° C. for 5 hours. The reaction mixture was poured into ice-water (300 ml) and extracted twice with ethyl acetate (200 ml). The extract was washed with saturated aqueous sodium chloride, dried over magnesium sulfate and evaporated in vacuo. The resulting residue was chromatographed on silica gel (150 g) eluting with a mixture of dichloromethane and acetone (2:1, V/V). The fractions containing the desired compound were collected and evaporated in vacuo to give (2S,4S)-2-[(2S)-2-(hydroxymethyl)pyrrolidin-1-yl]methyl-1-(4-nitrobenzyloxycarbonyl)-4-(triphenylmethylthio)pyrrolidine (5.75 g).
