Procedure:
To a solution of 4-[(2,4-dichloro-3-fluorophenyl)carbonyl]-2-piperazinone (I37) (0.146 g, 0.5 mmol) in Dichloromethane (DCM) (3 mL) was added triethyloxonium tetrafluoroborate (0.100 g, 0.525 mmol). The solution was then stirred, under argon, for 10 minutes before 5-fluoro-2-pyridinecarbohydrazide (I24) (0.093 g, 0.600 mmol) was added. The solution was then stirred for a further hour before the solvent was concentrated and n-butanol (3.00 mL) was added. The solution was then stirred, under argon and reflux, for 3 hours before being cooled to room temperature. The solvent was then evaporated in vacuo and the remaining residue was purified by flash chromatography (Biotage SP4, 25M cartridge) with a gradient of 0-10% 2M NH3/MeOH in DCM. TLC confirmed product location and the solvent from the combined fractions was evaporated in vacuo. The remaining residue was then further purified by mass-direct automated HPLC, and the solvent evaporated in vacuo. The remaining solid was then triturated with ether and dried in a vac-oven to yield the product in 0.045 g.

Procedure:
In a dry 3-necked, round bottomed flask, equipped with a magnetic stirrer, a thermometer, a nitrogen inlet tube and the dropping funnel containing the orotoyl bromide solution, 9.84 g (75 mmol) of Isoleucine is suspended, with stirring, in 100 mL of dry DCM. To this suspension a catalytic amount (˜0.1 mmol) of DMAP is also added. The suspension is stirred in a dry ice and acetone bath to a temperature of about −15° C. When the target temperature is reached the drop wise addition of orotoyl bromide is commenced. Addition of orotoyl bromide continues, with constant cooling and stirring, until all of the orotoyl bromide is added, after which the reaction is allowed to warm to room temperature with constant agitation. The solution is then filtered to remove any remaining Isoleucine and the volatile DCM is removed from the filtrate under reduced pressure, the remainder is then purified by flash chromatography (ethyl acetate/hexanes; 1/5), yielding 2-(2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxamido)-3-methylpentanoic acid.

Procedure:
A 1000 mL double jacketed glass reactor equipped with a mechanical stirrer, a Pt-100 thermometer, a reflux condenser, a dropping funnel and a nitrogen inlet was charged with 50.0 g (483 mmol) of L-Prolinamide and 230 mL of methylenechloride. The suspension was stirred and treated with 51.2 g (504 mmol) of triethylamine and cooled to −40° C. to −50° C. and a solution of 58.0 g (508 mmol) of chloroacetylchloride in 50 mL of methylenechloride was added within 60 to 90 min. The dropping funnel was rinsed with 5 mL of methylenechloride. The suspension was warmed up to −5° C. to 0° C. within 1 h. The resulting (S)-1-(2-Chloro-acetyl)-pyrrolidine-2-carboxylic acid amide was dehydrated while adding the solution of the Vilsmeier-Reagent from the first reaction within 1 to 15 min at −5° C. to 5° C. The dropping funnel was rinsed with 5 mL of methylenechloride and the resulting mixture was stirred for about 1 h at −5° C. to 5° C. The reaction mixture was then poured onto 175 mL of water within 10 to 30 min and at a temperature of 5° C. to 20° C. The reactor was rinsed with 5 mL of methylenechloride. The mixture was stirred at RT for at least 30 min. The phases were separated and the aqueous phase was twice extracted with a total of 170 mL of methylenechloride. The organic phases were unified and washed with 88 mL of water. The resulting organic phase was concentrated under vacuum (500 mbar to 50 mbar) at 20° C. to 50° C. The resulting oil was treated within 10 to 30 min with 325 mL of isopropanol and heated to 45° C. Subsequently, the solution was again cooled to 25° C. to 30° C. within 20 min and inoculated where after the product started to precipitate. The suspension was stirred for 1 h at this temperature and then cooled down to −15° C. to −20° C. within 4 h. The crystallization was completed by the addition of 85 ml of n-heptane and the mixture was kept stirring for another 2 h. The precipitate was filtered with suction, the filter cake was washed with cold (−10° C. to 20° C.) n-heptane (140 mL) and dried to constant weight (50° C., 50 mbar, 3 h) to afford 62.6 g of (S)-1-(2-chloroacetyl)-pyrrolidine-2-carbonitrile. (Yield: 83%, assay: 100% (m/m) based on HPLC). The HPLC analysis was performed with an external standard of pure (S)-1-(2-chloroacetyl)-pyrrolidine-2-carbonitrile.
