Procedure:
To a solution of 2 g of 3,4-diaminophenol in 150 cm3 of acetone are added 2.264 cm3 of triethylamine and 3.425 g of 2,6-difluorobenzenesulfonyl chloride. The reaction medium is stirred at a temperature in the region of 20° C. overnight. The insoluble material is filtered off and rinsed with three times 50 cm3 of acetone, and the filtrate is evaporated to dryness under reduced pressure (3.5 kPa). The residue is taken up in 300 cm3 of dichloromethane, washed with three times 50 cm3 of water, dried over magnesium sulfate, filtered and evaporated to dryness under reduced pressure. After flash chromatography on a column of silica [eluent: dichloromethane/methanol (95/5 by volume)], 650 mg of 3,4-diaminophenyl 2,6-difluorobenzenesulfonate are obtained in the form of a black resin, the characteristics of which are as follows:

Procedure:
A solution containing (R)-ethyl 2-amino-5-methylcyclopent-1-enecarboxylate (161.61 g, 955.024 mmol) and ammonium formate (90.3298 g, 1432.54 mmol) in formamide (303.456 mL, 7640.19 mmol) was heated to an internal temperature of 150° C. and stirred for 17 hours. The reaction mixture was cooled, and transferred to a 2 L single extracted flask. Then excess formamidine was removed by high vacuum distillation. Once formamidine stopped coming over, the remaining oil in the still pot was dissolved in DCM and washed with brine (3×200 mL). The combined aqueous washes were extracted with DCM. The combined organic extracts were dried (Na2SO4), filtered, and concentrated. The resulting oil was dissolved in minimal DCM, and this solution was added using a separatory funnel to a stirred solution of ether (about 5 volumes of ether vs. DCM solution), causing some precipitate to form. This precipitate was removed by filtration through a medium fit funnel which was rinsed with ether and disposed. The filtrate was concentrated, the trituration from ether repeated two more times and then dried on high vacuum line to give (R)-5-methyl-6,7-dihydro-5H-cyclopenta[d]pyrimidin-4-ol (93.225 g, 65.00% yield) as a pasty solid.

To a solution of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diaza-bicyclo[3.2.1]octane-2-carboxylic acid (1.0 g, 6.0 mmol) in THF (30 mL) was added 1,1′-carbonyldiimidazole (1.6 g, 7.2 mmol) at 0° C. The reaction mixture was stirred at rt for 1 h, then, formohydrazide (1.1 μg, 18.1 mmol) was added rapidly at rt. The reaction mixture was stirred at rt for 3 hrs and then diluted with EtOAc (100 mL). The combined organic layer was washed with saturated sodium chloride (10 mL), dried over Na2SO4, and concentrated to afford (2S,5R)-6-(benzyloxy)-N′-formyl-7-oxo-1,6-diaza-bicyclo[3.2.1]octane-2-carbohydrazide (1.6 g), which was used directly in the next step.

Procedure:
3-tert-Butoxycarbonylamino-azetidine-1,3-dicarboxylic acid 1-tert-butyl ester 3-ethyl ester (520 mg; 1.5 mmol) in THF (15 ml) is refluxed with LiBH4 (67 mg; 3 mmol) for 20 minutes. The reaction mixture is diluted with water, acidified with 2N HCl to destroy excess of LiBH4, neutralized again with 2N Na2CO3 and extracted with TBME three times. The organic phases are combined, dried over Na2SO4 and evaporated to dryness, yielding the desired product as colorless crystals. 1H-NMR (400 MHz; DMSO-d6: 7.27 (bs, 1H); 5.07 (bt, 1H); 3.78 (bs, 4H); 3.46 (d, 2H); 1.40 (s, 9H); 1.38 (s, 9H).
