Procedure

To a solution of 4-benzyloxy-N-[2,2-diethoxy-2-(2-isopropylamino-6-methyl-pyrimidin-4-yl)-ethyl]-3-ethyl-5-methyl-benzamide (346 mg, 0.65 mmol) in THF (8 mL), 25% aq. HCl (500 μL) is added and the mixture is stirred at 65° C. for 18 h. The mixture is cooled to 0° C., neutralized by adding 1 N aq. NaOH solution and extracted twice with EtOAc. The combined org. extracts are dried over Na2SO4, filtered and concentrated to give crude 4-benzyloxy-3-ethyl-N-[2-(2-isopropylamino-6-methyl-pyrimidin-4-yl)-2-oxo-ethyl]-5-methyl-benzamide (325 mg) as a yellow oil; LC-MS: tR=0.94 min, [M+H]+=461.13.
