Procedure

(1S,1aR,7bS)-4,7-difluoro-1,1a,2,7b-tetrahydrocyclopropa[c]chromene-1-carboxylic acid (50 mg, 0.22 mmol, ee ˜90%) was mixed with toluene (1 ml), triethylamine (0.034 ml, 1.1 eq), 3-amino-5-cyclopropyl-1H-pyrazole (30 mg, 1.1 eq), DPPA (0.054 ml, 1.1 eq). The reaction mixture was then heated at stirring at 110° C. for 3 h. The reaction mixture was concentrated by rotary evaporation and two compounds were separated by column chromatography on silica (50 g, ethylacetate/hexane 1:3) to give 3 mg of the title product. The structure assignment was proved by 13C, gHMBC, gHMQC and NOESY NMR experiments.
