Procedure:
A mixture of hydroxylammonium chloride (1.8 g), sodium hydrogencarbonate (2.8 g) and dimethyl sulfoxide (15 mL) was stirred at 40° C. for 30 min, 4′-{[6-ethyl-3-[2-(4-methoxyphenyl)-2-oxoethyl]-2,4-dioxo-3,4-dihydrothieno[2,3-d]pyrimidin-1(2H)-yl]methyl}biphenyl-2-carbonitrile (1.38 g) was added, and the mixture was stirred at 90° C. for 16 hr. The reaction mixture was diluted with chloroform, washed successively with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was dissolved in methylene chloride (15 mL), N,N′-carbonyldiimidazole (0.28 g) and then 1,8-diazabicyclo[5.4.0]undec-7-ene (0.23 mL) were added, and the mixture was stirred at room temperature for 2 hr. The reaction mixture was diluted with chloroform, washed successively with saturated aqueous potassium hydrogensulfate solution and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The obtained residue was purified by preparative HPLC to give the title compound as colorless crystals (0.27 g, 17%).

Procedure:
The CBZ group of (S)-phenylmethyl-[1-methyl-2-oxo-2(1H-pyrrol-1-ylamino)ethyl]carbamate (5.50 g) was cleaved in a minimal volume of methanol over 5% Pd-C (0.83 g) with H2 (g) (468 ml) under atmospheric conditions. The catalyst was removed by filtration through a pad of celite and the filter cake was washed with methanol. The combined filtrate was concentrated and the residue purified via flash column chromatography (silica gel, 20% EtOH/ethyl acetate) to afford 2.62 g of the desired product as an oil which crystallized on standing, m.p. 81°-82° C.

Procedure:
N-butyl lithium (1.6 mol solution in hexane, 19.4 ml) is added dropwise at 0° C., under a nitrogen atmosphere, to a solution of diisopropylamine (4.4 ml) in tetrahydrofuran (100 ml), and the mixture is stirred for 20 minutes. The solution is cooled to -78° C. and then 5 g of 4,5-dichloro-6-ethylpyrimidine in solution in 10 ml of tetrahydrofuran are added dropwise. The mixture is stirred at -78° C. for one hour and then brought to room temperature over a period of 2 hours. After the addition of water (200 ml), the mixture is extracted with ethyl acetate and the organic phase is dried over sodium sulfate and concentrated. Chromatography on silica gel (eluant: ethyl acetate/hexane 1:10) yields 3.8 g (71% of the theoretical yield) of 4,5-dichloro-6-isopropylpyrimidine in the form of a yellow oil.

Procedure:
5% Palladium on charcoal catalyst (2 g) is added to a solution of 5-benzyloxy-4-cyclopentyloxy-2-trityloxymethylpyridine (24.2 g) in ethanol (500 mL) and the mixture stirred at room temperature under a hydrogen atmosphere for 3 hours. After filtering the filtrate is concentrated in vacuo to give a colourless oil which is purified by flash chromatography (n-pentane/ethyl acetate 7:3 v/v as eluent on silica) to give 4-cyclopentyloxy-5-hydroxy-2-trityloxymethylpyridine (18.8 g) as a colourless foam.

Procedure:
50 moles (9.3 g) Ala-Pro were suspended in 100 ml ethanol, combined with 75 moles (15.5 g) 2-oxo-4-phenyl-butyric acid ethyl ester and 18 g molecular sieve 3 A and agitated for 2 hours under anhydrous conditions. One teaspoon of dehydrated Raney nickel and 15 g molecular sieve 3 A were now added, briefly reacted and subsequently hydrogenated for 22 hours under an atmosphere of 4 bars of H2. The reaction mixture was filtered and evaporated to concentrate it to a small volume. Conversion (according to HPLC) relative to Ala-Pro used: 76.7%, product yield (according to HPLC): 35%. The residue was taken up is 250 ml ethanol and adjusted to pH 4.25 with conc. HCl (an aliquot was removed for this purpose, diluted with water and the pH was adjusted, then the entire amount was calculated). The solution was evaporated to low bulk under reduced pressure at 40° C. to 50 g, filtered by Celite and diluted to 100 ml total volume with ethyl acetate. 5.2 g maleic acid dissolved in ethyl acetate+ethanol were added and seeded with enalapril maleate. The crystallizate formed was separated off and dried.
