Versuchsvorschrift
3-Isobutyl-1-cyclobutenecarboxylic acid (188 g) and tetrahydrofuran (2000 mL) were mixed. To the mixture was added 5 w/w % rhodium on activated carbon (5.64 g). The resulting mixture was stirred at RT for 7 hr under hydrogen atmosphere (1 atm). The 5 w/w % rhodium on activated carbon was filtered off and the filtrate was concentrated in vacuo to give the title compound (134.06 g) as a crude product.
