Procedure

4-[5-(Cyclopropylmethoxy)-1,3-benzodioxol-4-yl]-6-methyl-5-{[2-(trimethylsilyl)ethoxy]methyl}-5H-pyrrolo[3,2-d]pyrimidine-7-carboxylic acid from example D.c1 (3.98 g; 8.0 mmol), triethylamine (2.43 g; 24.0 mmol) and HOBt (1.08 g; 8.0 mmol) is stirred in dry dichloromethane (40 mL) for 30 min, before addition of EDC (1.84 g; 9.6 mmol). The reaction mixture is stirred for one hour at ambient temperature. After addition of tert-butyl 4-amino-piperidine-1-carboxylate hydrochloride (2.27 g; 9.6 mmol) the reaction mixture is stirred at ambient temperature until the starting material is consumed according to LC-MS and chromatographed on silica gel (ethylacetate/cyclohexane 1:1) to yield the title compound as colorless foam.
