Procedure:
To a dichloromethane (377 ml) solution of ethyl (2E)-3-(3-amino-5-chloropyridin-2-yl)acrylate (37.7 g) and trifluoroacetic acid (12.7 ml) was added tert-butyl 4-oxopiperidine-1-carboxylate (49.7 g). After stirring at room temperature for 15 minutes, sodium triacetoxyborohydride (70.5 g) was added, and stirred at 40° C. for 1.5 hours. After the reaction solution was brought back to room temperature, dichloromethane and a saturated aqueous sodium hydrogen carbonate solution were added and the solution was separated, and the aqueous layer was extracted with dichloromethane. The collected organic layer was dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The resulting residue was dissolved in methanol (2 ml), and 1.7% palladium-fibroin (10 g) was added, followed by stirring at room temperature for 18 hours under a hydrogen atmosphere. The reaction solution was filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography to afford tert-butyl 4-{[5-chloro-2-(3-ethoxy-3-oxopropyl)pyridin-3-yl]amino}piperidine-1-carboxylate (55.3 g).

After stirring for 48 hours at a temperature in the region of 20° C., the reaction mixture is filtered. The filtrate is concentrated under reduced pressure (1 kPa) at a temperature in the region of 50° C. The residue obtained is taken up in ethyl acetate and water and the phases are separated after settling has taken place. The organic phase is washed with sodium chloride solution, dried over magnesium sulfate and chromatographed on a column of alumina, eluting with successive mixtures of ethyl acetate/cyclohexane (50/50 by volume). The fractions containing the expected product are purified by chromatography on a column of silica gel, eluting with ethyl acetate. The fractions containing the expected product are combined and then concentrated under the above conditions. 0.356 g of tert-butyl N-[(4RS)-4-(4-pyridylsulphanylmethyl)-4,5-dihydro-2-thiazolyl]carbamate is obtained in the form of a yellow oil [1H NMR spectrum (300 MHz, (CD3)2SO-d6, δ in ppm): 1.42 (s: 9H); 3.09 (dd, J=11.5 and 6 Hz: 1H); 3.29 (mt: 2H); 3.40 (dd, J=11.5 and 8 Hz: 1H); 4.25 (mt: 1H); 7.35 (dd, J=5 and 1.5 Hz: 2H); 8.40 (dd, J=5 and 1.5 Hz: 2H); from 9.70 to 10.00 (broad unresolved complex: 1H)].

Procedure:
To a solution of 4.65 g (29.0 mmol) of 4-carbomethoxytetrahydro-3-thiophenone in 20 ml of dry DMSO cooled in a cold-water bath at 12° C. under argon was added 1.73 g (32.0 mmol) of sodium methoxide. The mixture was stirred 30 minutes and a solution of 4.97 g (35.0 mmol) of methyl iodide in 1 ml of dry DMSO was added dropwise. The mixture was stirred overnight at room temperature, than diluted with water (60 ml) and extracted with methylene chloride (3×75 ml). The extract was washed with water (50 ml) and brine, dried over sodium sulfate, filtered, and concentrated in vacuo to give 5.4 g of an oil. The oil was flash chromatographed on silica gel eluting with 3:1 hexane:ether to give 1.49 g (30%) of the product as an oil; NMR (deuteriochloroform): δ 3.76 (S, 3H), 3.70 (m, 1H), 3.50 (dd, 1H), 3.30 (dd, 1H), 2.83 (d, 1H), 1.46 (S, 3H).

Procedure:
To a solution of commercially available tert-butyl 4-oxo-1-piperidine carboxylate (400 mg, 2 mmol) in methanol (1 ml) and 2,4-di-chlorobenzylamine (0.135 ml, 1 mmol) in methanol (1 ml) was added acetic acid in methanol (1 M, 1.34 ml) followed by NaCNBH3 in methanol (0.3 M, 4.4 ml). The resulting solution was stirred at room temperature. After 24 h, water (2 ml) was added, and the mixture was stirred for 1 h, before it was concentrated. The resulting oil was redissolved in diethyl ether (20 ml), extracted with HCl (0.1 N, 1×15 ml). The aqueous layer was washed with diethyl ether (10 ml) and treated with 0.2 N NaOH until basic (pH>8), before extracted with dichloromethane (20 ml). The organic layer was dried (Na2SO4), filtered, and concentrated to give tert-butyl 4-((2,4-di-chlorophenyl)methyl)amino-piperidine carboxylate. Yield: 97 mg. To a solution of tert-butyl 4-((2,4-di-chlorophenyl)methyl)amino-piperidine carboxylate (50 mg, 0.14 mmol) in dichloromethane (6 ml) was added diisopropylethylamine (0.070 ml, 0.4 mmol) followed by 4-methoxyphenylacetyl chloride (0.055 ml, 0.35 mmol). The reaction mixture was stirred at room temperature. After 18 h, water (2 ml) was added. The mixture was stirred for another 2 h. The mixture was sequentially washed with HCl (0.2 N, 2×15 ml), NaOH (0.2 N, 2×15 ml), and water (10 ml), dried (Na2SO4), filtered and concentrated to give N-((2,4-di-chlorophenyl)methyl)-N-(1-(tert-butyloxycarbonyl)piperidin-4-yl)-4-methoxyphenylacetamide. The crude product was used without any further purification. N-((2,4-Di-chlorophenyl)methyl)-N-(1-(tert-butyloxycarbonyl)piperidin-4-yl)-4-methoxyphenylacetamide was dissolved in diethyl ether (2 ml) and HCl (1 ml, 4 M in dioxane) was added. The reaction mixture was stirred at room temperature. After 2.5 h, NaOH (1 ml, 6 N) was added followed by dichloromethane (10 ml). The mixture was extracted with water (2×15 ml), dried (Na2SO4), filtered to give a clear solution. The solution was added on to a column carrying strongly acidic cation exchange resin (0.3 mmol/g resin), which was washed with methanol (3×6 ml), and eluted with 10% NH3 in methanol, and concentrated to give the title compound.

Procedure:
The resultant crude protected cephaloglycin mixture is worked up by treating with a mixture of 27 ml ice-water and 6 ml concentrated HCl and stirred for 15 minutes while cooling with ice. The aqueous phase is separted off and the organic phase is back-extracted with 2 ml ice-water. The combined aqueous phases are heated to 25° C. and TEA is added until a pH value of 4.5/4.7 is reached. The title compound is obtained in the dihydrate form by standing the mixture 30 minutes, filtering the crystals and washing then with 30 ml ice-water and 30 ml 80% acetone, followed by drying.
