Versuchsvorschrift

To a solution of (3S*,5R*)-3-Amino-5-{cyclopropyl-[3-methoxy-5-(3-methoxy-propoxy)-benzyl]-carbamoyl}-piperidine-1-carboxylic acid tert-butyl ester (50 mg, 0.10 mmol) in DMF (0.5 mL) are added i-Pr2NEt (26 uL, 0.15 mmol) and 4,6-dichloropyrimidine (23 mg, 0.15 mmol). After stirring for 16 h, the reaction mixture is quenched by H2O (30 mL) and extracted with EtOAc/Et2O (c.a. 1:1, 60 mL). The organic phase is successively washed with 5% KHSO4aq, 5% NaHCO3aq, H2O, and brine, then dried over Na2SO4. The solution is filtered and the solvent is evaporated in vacuo. The residue is purified by silica gel column chromatography to give Boc protected title compound. MS: 604 (Cl35) [M+H]+; tR (HPLC, ACQUITY UPLC™ BEH C18 1.7 μm, 50×2.1 mm; 5% CH3CN+0.1% TFA/H2O+0.1% TFA for 0.5 min then 5-100% CH3CN+0.1% TFA/H2O+0.1% TFA for 5 min then 100% CH3CN+0.1% TFA for 1.5 min, flow 0.5 ml/min): 3.88 min. The Boc protected compound is treated with 4N HCl-1,4-dioxane to give the title compound as a white amorphous solid. MS: 504 (Cl35) [M+H]+; tR (HPLC, ACQUITY UPLC™ BEH C18 1.7 μm, 50×2.1 mm; 5% CH3CN+0.1% TFA/H2O+0.1% TFA for 0.5 min then 5-100% CH3CN+0.1% TFA/H2O+0.1% TFA for 5 min then 100% CH3CN+0.1% TFA for 1.5 min, flow 0.5 ml/min): 2.66 min.
