Versuchsvorschrift

(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), 2-amino-4-(4-chlorophenyl)-1,3-thiazole (52 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 the product was crystallized from ethanol and collected by filtration to give 50 mg of the product as white solid.
