Procedure

tert-Butyl 4-[({4-[2-(cyclopropylmethoxy)-5-(2-methyl-1,3-dioxolan-2-yl)phenyl]-6-methyl-5H-pyrrolo[3,2-d]pyrimidin-7-yl}carbonyl)amino]piperidine-1-carboxylate from example D.e55 (1.77 g; 2.99 mmol) is dissolved in dry acetone (30 mL). After addition of 4M HCl in dioxane (3 mL) the stirred mixture is gently refluxed until the starting material is consumed according to LC-MS. At ambient temperature the product is precipitated by addition of tert.-butyl methyl ether, isolated by suction filtration, washed with several portions of tert.-butyl methyl ether and dried in high vacuo at 40° C. to yield 1.40 g of the title compound as pale yellow solid.
