Reaction Steps
To a solution of 4-(3-{2-[tert-butoxycarbonyl-(3,4-difluoro-phenyl)-amino]-acetylamino}-4-methyl-benzyl)-piperazine-1-carboxylic acid tert-butyl ester (0.100 g) in MeOH (3 ml) was added HCl (2ml of 4M solution in dioxane). After standing for several hours, a solid was filtered off, washed with acetone and dried in vacuo. The solid was re-suspended in acetone, sonicated for 5 min filtered and dried to afford the title compound (0.043 g, 51%).
