Procedure:
Pyridine (0.4 mL) was added to a solution of methyl 4-amino-2-chlorobenzoate (0.3 g) in CH2Cl2 (10 mL) at 0° C. under N2. N,N-Dimethylsulfamoyl chloride (0.21 mL) was added and the mixture was stirred at room temperature for 16 hours and refluxed for 5 hours.

Procedure:
30.7 g (0.12 mol) of pentaerythritol triallylether was dissolved in 100 ml of dry THF and 4.4 g (0.18 mol) of NaH was added in small portions while stirring. After gas evolution had ceased, 16 ml (0.18 mol) of allyl bromide was added and the reaction mixture was stirred overnight at room temperature. In order to drive the reaction to completion, it was subsequently brought to reflux and stirred for 1 hr. The precipitated salts were removed by filtration over ca. 1 cm of Celite 545 and the solvent and excess allyl bromide were evaporated, yielding 35.3 g (99.5%) of a pale yellow oil. The raw product was dissolved in 100 ml of diethyl ether and washed subsequently with 50 ml of 0.1 M aqueous KHSO4 and 50 ml of saturated aqueous NaHCO3 solution. Drying the organic layer with MgSO4 and evaporation of the solvent yielded 34.4 g (97%) of the pure product.

Procedure:
Hydrogen chloride (4N) in ethyl acetate (1.5 ml) was added to a solution of crude 3-benzyloxy-1-(tert-butoxycarbonyl)-pyrrolidine (705 mg) in diethyl ether (3 ml) and the mixture was stirred for 15 minutes. Reaction was quenched with water, and the solution was washed with diethyl ether. After addition of aqueous sodium hydroxide to make the solution basic, the solution was extracted with diethyl ether and the organic layer was washed with brine and dried over sodium sulfate. Removal of the solvent under reduced pressure afforded 3-benzyloxy-pyrrolidine (182 mg, 37%).
