Procedure:
A solution of 14.9 g of chloroacetyl chloride in 25 ml of methylene chloride was added to a stirred solution of 15.0 g of 1-(3-aminopropyl)imidazole in 75 ml of methylene chloride at 0° C. The rate of addition was controlled to keep the reaction temperature below 15° C. During the course of the reaction a brown gummy viscous oil separated out of solution. Approximately two-thirds of the way through the addition, 50 ml of 20% NaOH was added to the mixture, and the oil went into solution. After the addition was completed, the mixture was stirred at room temperature for 15 minutes. The water layer was removed, the organic layer was dried over MgSO4 and filtered, and the solvent was removed under vacuum to give a yellow oil. The oil was dissolved in 30 ml of water and the pH was adjusted to approximately 3.0. Analysis for organic chloride indicated dimerization and/or trimerization had occurred.

Procedure:
tert-Butyl-2,8-diazaspiro[4.5]decane-2-carboxylate (10.403 mmol, 1 equiv.) and N-ethyl-diisopropylamine (41.608 mmol, 4 equiv.) were placed in 2-propanol (20 ml). 4-Chloropyridine (31.206 mmol, 3 equiv.) was added, and the mixture was heated for 16 hours at 90° C. Saturated sodium hydrogen carbonate solution (50 ml) was then added, and the phases were separated. The aqueous phase was extracted with ethyl acetate (4×50 ml), and the combined organic phases were washed with saturated NaCl solution (50 ml) and dried over magnesium sulfate. After purification by column chromatography (ethyl acetate/DCM/methanol/ammonia (25% aq), 100:100:25:1), the desired product was obtained in the form of a yellow oil. Yield: 1.8 g (55%)

Procedure:
To a suspension of 5 g of trimetrexate hydrate in 30 ml of 2-propanol and 15 ml of water was added 2.10 g of trifluoroacetic acid (approximately a 40% excess). The solid partly dissolved, but new crystals came out before it was completely gone. The mixture was heated to near reflux to give a clear dark yellow-green solution. To this was added 100 ml of 2-propanol. The product crystallized rapidly, and was collected after ice-cooling for 1 hour, washed with ice-cold 2-propanol and dried in air at 50% relative humidity to give 5.95 g of greenish-yellow crystals.

Procedure:
9.3 g of 2,2-difluoroethenyl tosylate, which had been synthesized by a conventional technique, was dispersed in 17 g of water and 37 g of methanol, after which 4.7 g of sodium hydrogen sulfite and 0.5 g of benzoyl peroxide were added. The reaction mixture was stirred at 80° C. for 40 hours. The reaction solution was allowed to cool, after which methanol was distilled off in vacuum. Toluene was added, followed by separatory operation to separate a water layer. A saturated sodium chloride aqueous solution was added to the water layer whereupon white crystals settled out. The crystals were collected by filtration, washed with a small volume of saturated sodium chloride aqueous solution and then dried in vacuum, obtaining the target compound, sodium 1,1-difluoro-2-tosyloxyethanesulfonate. White crystals, 2.5 g (yield 16%).

Procedure:
Borane dimethyl sulfide complex (2M in THF, 17.3 mL) was added dropwise to an ice cold solution of 3-(2-(tert-butyldimethylsilyloxy)ethylthio)benzoic acid (example 65, step a) (2.16 g) in THF (50 mL). The reaction was allowed to warm to RT, then heated at reflux for 2 h. The reaction was cooled in an ice bath and aqueous HCl solution (2M, 50 mL) was added dropwise. The resulting mixture was stirred overnight. The reaction was concentrated to half its original volume and the resulting aqueous extracted with DCM (3×100 mL). The combined organics were washed with brine (100 mL), dried over sodium sulphate, filtered and evaporated. The residue was purified by silica gel chromatography eluting with 4:1 isohexane:ethyl acetate to 100% ethyl acetate gradient. The fractions containing product were combined and evaporated to give the subtitled compound as a clear oil. Yield 0.77 g.
