反応手順

4-Chloro-1H-pyrrolo[2,3-d]pyrimidine (2.10 g, 13.6 mmol) was dissolved in 1-butanol (60.0 mL) and N,N-diisopropylethylamine (3.57 mL, 20.5 mmol) was added followed by (S)-(+)-1-aminoindan (1.93 mL, 15.0 mmol). The mixture was heated to reflux for 60 h, cooled down to rt and the solvent was evaporated to dryness. The residue was purified via silica gel chromatography eluting with a gradient of 0 to 100% EtOAc in DCM to afford the title compound (2.72 g, 80%). LC/MS: Rt=1.42 min, ES+ 251 (AA standard).
