To a solution of <strong>[159622-10-3](1R,2S)-1-(tert-butoxycarbonylamino)-2-vinylcyclopropanecarboxylic acid</strong> (7.5 g, 33 mmol) in DMF (50 mL) was added CDI (10.69 g, 66 mmol) and the reaction mass was heated at 55° C. for 4 h. To this reaction mass was added 1-fluoromethylcyclopropane-1-sulfonamide (6.5 g, 42.9 mmol) followed by DBU (6 mL, 42.9 mmol). The reaction mixture was stirred at 55° C. for 18 h. The solvent was evaporated under reduced pressure and the residue was diluted with water and acidified to pH2 by using 1.5 N HCl solution. The precipitated solid was filtered and washed with water to get desired compound (11.5 g, 96percent) as off-white solid. MS: MS m/z 361.4 (M+?1). |

To this reaction mass was added 1-fluoromethylcyclopropane-1-sulfonamide (6.5 g, 42.9 mmol) followed by 1,8-diazabicyclo[5.4.0]undec-7-ene ("DBU", 6.0 mL, 43 mmol). The reaction mixture was stirred at 55° C. for 18 h. The solvent was evaporated under reduced pressure and the residue was diluted with water and acidified to pH ?2 by using aq. 1.5 N HCl solution. The precipitated solid was isolated via filtration and washed with water to afford tert-butyl (1R,2S)-1-(1-(fluoromethyl)cyclopropylsulfonylcarbamoyl)-2-vinylcyclopropylcarbamate as off-white solid (11.5 g, 96percent). MS: MS m/z 361.4 (M+-1). |
