Procedure

A solution of tert-butyl 4-{[(4-[5-(cyclopropylmethoxy)-1,3-benzodioxol-4-yl]-6-methyl-5-{[2-(trimethylsilyl)ethoxy]methyl}-5H-pyrrolo[3,2-d]pyrimidin-7-yl)carbonyl]amino}piperidine-1-carboxylate from example D.d1 (3.74 g; 5.5 mmol), tetrabutylammonium fluoride trihydrate (5.21 g; 16.5 mmol) and ethane-1,2-diamine (0.50 g; 8.25 mmol) in tetrahydrofurane (40 mL) is heated to gentle reflux until the starting material is completely consumed according to LC-MS. The crude is purified by column chromatography on silica gel (ethyl acetate/cyclohexane—1:1 to 2:1) to yield the title compound as colorless solid.
