실험 절차

Starting from 2,4-dichloro-6,7-dihydro-thieno[3,2-d]pyrimidine and 1-amino-cyclopropanmethanol the two enantiomers of [1-(2-chloro-5-oxo-6,7-dihydro-5H-5λ4-thieno[3,2-d]pyrimidin-4-ylamino)-cyclopropyl]-methanol may be prepared as described in Example 28 (cf 2.1.2). The enantiomers may be separated by chiral HPLC (column Diacel IA, 250×4.6 mm, 5 m, eluant: (hexane+cyclohexylamine (0.2%))/ethanol (80/20), flow rate: 1 ml/min): enantiomer 1: RT=11.1 min; enantiomer 2: RT=16.5 min.
