Reaction Conditions

Reaction Steps

To a stirred suspension of (RS)—N-[4-(2-amino-4,5-dihydro-oxazol-4-yl)-phenyl]-4-chloro-benzamide (50 mg) in methanol (3 ml) were added ammonium formate (100 mg) and palladium on charcoal (13 mg, 10 wt %) and the mixture was heated at 60° C. for 2 hours. The mixture was then cooled to room temperature, filtered through celite and the filtrate was concentrated in vacuo. The residue was taken up in ethyl acetate/THF (1:1) and this solution was washed sequentially with saturated aq. sodium bicarbonate solution and saturated brine. The organic phase was then separated, dried over sodium sulphate and concentrated in vacuo. The residue was purified by column chromatography (Isolute® Flash-NH2 from Separtis; gradient: heptane/dichloromethane/methanol) to give (RS)—N-[4-(2-amino-4,5-dihydro-oxazol-4-yl)-phenyl]-benzamide (20 mg, 45%) as a white solid. MS (ISP): 282.1 ([M+H]+).
