Reaction Steps

305 mg of rac-benzyl {2-[({8-[(2,6-difluorobenzyl)oxy]-2-methylimidazo[1,2-a]pyridin-3-yl}-carbonyl)amino]-3-isopropoxypropyl}carbamate (intermediate 116A; 0.54 mmol) were initially charged in 46 ml of ethanol, 44 mg of 10% palladium on activated carbon were added and the mixture was hydrogenated under hydrogen standard pressure for 4 hours. The reaction mixture was filtered and concentrated and the residue was purified by preparative HPLC (column: Macherey-Nagel VP 50/21 Nucleodur 100-5 C18 HTEC, 50×21 mm; mobile phase: gradient with 0.1% strength aqueous ammonia solution and methanol). This gave 127 mg of the title compound (54% of theory).
