Procedure:
A mixture of acetic anhydride (44.5 ml) and formic acid (22.3 ml) was stirred at room temperature for an hour. To this mixture was added 5-amino-1-(2-hydroxyethyl)pyrazole (30 g) at 0°-10° C., and the mixture was stirred under ice-cooling for 30 minutes. The mixture was poured into ice-cooled water, adjusted to pH 10.5 with 40% potassium carbonate solution, and stirred under ice-cooling for 30 minutes. The mixture was extracted with a mixture of tetrahydrofuran and ethyl acetate 6 times. The organic layer was dried over magnesium sulfate, and evaporated in vacuo to give 5-formamido-1-(2-hydroxyethyl)pyrazole (30.8 g).

Procedure:
Dipropylamine (22.3 g, 0.22 mol) was added to a stirred solution of diethyl bromomalonate (47.8 g, 0.20 mol) in THF (400 mL) and the solution was stirred for 18 hours at room temperature. The precipitate of dipropylamine hydrobromide was filtered off and washed with THF. The THF phase was evaporated and the residual oil was partitioned between ethyl acetate (200 mL) and sodium hydroxide solution (10 mL of 4 N). The ethyl acetate phase was separated, washed with water (2×10 mL), and the solvent was removed under reduced pressure. The residual oil was dissolved in an equal volume of hexane and was applied to a silica gel column (420 g) which was eluted initially with ethyl acetate:hexane (1:20). The concentration of ethyl acetate in the eluant was increased slowly until all the diethyl (dipropylamino)malonate was eluted from the column. Fractions containing the compound as determined by TLC and GC were pooled and the solvent was removed to give diethyl (dipropylamino)malonate as an oil in 80-90% yield.

Procedure:
(1RS,2SR,3RS)-3-(2-tert-butoxycarbonylmethoxy-4-methoxyphenyl)-1-(3,4-methylenedioxyphenyl)-5-(prop-1-yloxy)indane-2-carboxylic acid (100 mg, 0.18 mmol), triphenylphosphonyl azide (0.03 ml, 0.18 mmol), and triethylamine (73 mg, 0.72 mmol) were dissolved in dry benzene (4 ml) and heated at 40° C. for 2 h and at 75° C. for 2 h. The reaction mixture was then partitioned between 1 N HCl and ethyl acetate. The organic layer was washed with water and brine, dried (MgSO4 anhyd.), filtered and evaporated to give the corresponding isocianate as a colorless oil. After purification by column chromatography (silica gel, ethyl acetate/hexane 30:70), the isocianate (100 mg) thus obtained was dissolved in 1 M HC1 in dioxane (3 mL) and the mixture was heated at 80° C. overnight. The solvent was removed in vacuo, the residue was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried (MgSO4) and concentrated to give a colorless oil that was purified by HPLC (1:1 CNCH3 :H2O (containig 0.1% TFA)) to produce the desired product (40 mg, 42%) as an off-white solid, m.p. 181-182° C. (dec).
