Dioxane HCl (10 ml) was added to 1-(4-methyl-pyridin-3-yl)-3-[1-(2-trimethylsilanyl-ethoxymethyl)-1H-benzotriazol-5-yl]-imidazolidin-2-one (I-141a: 350 mg, 0.78125 mmol) and the resulting mixture was stirred room temperature for 12 hours. The reaction was monitored by TLC (10% MeOH in DCM). The reaction mixture was concentrated and washed with ether. The solid formed was collected and dried under reduced pressure to afford 230 mg of the product (89.4% yield).
