Reaction Steps

216 mg of rac-benzyl 1-[({8-[(2,6-difluorobenzyl)oxy]-2-methylimidazo[1,2-a]pyridin-3-yl}carbonyl)amino]-3-azabicyclo[4.1.0]heptan-3-carboxylate (Example 176A, 0.4 mmol, 1 equivalent) were reacted [0.2 equivalents of palladium on activated carbon (10%), reaction time: 16 h] and worked up analogously to Example 121 [After the separation by HPLC, the residue was taken up in ethyl acetate and washed twice with saturated aqueous sodium bicarbonate solution. The aqueous phase was extracted with ethyl acetate. The combined organic phases were dried over sodium sulphate, filtered and concentrated]. This gave 123 mg (74% of theory; 98%) of the title compound.
