Versuchsvorschrift

Dissolve 1.00 g (3.0 mmol) 4-chloro-5-(4-methoxyphenyl)-6-phenylfuro[2,3-d]pyrimidine in 10 ml DMF and add 1.15 g (8.9 mmol) DIEA. Add 0.45 g (5.9 mmol) 3-aminopropanol and then heat the mixture over a period of 2 h to 120° C. After cooling, dilute the mixture with ethyl acetate and wash successively with dilute hydrochloric acid and saturated sodium chloride solution. Dry the organic phase over magnesium sulphate and concentrate by evaporation. Purify the residue by RP-HPLC (column: Gromsil 250 mm×30 mm, 10 μm; acetonitrile/water gradient: 0-3 min 5% acetonitrile, 3-50 min 5%→98% acetonitrile, 50-55 min 98% acetonitrile). 671 mg (60% of theor.) 3-{[5-(4-methoxyphenyl)-6-phenylfuro[2,3-d]pyrimidin-4-yl]amino}propan-1-ol is obtained in the form of beige crystals.
