Reaction Steps

Stir a mixture of 400 mg (approx. 0.80 mmol) 6-{[5-(4-methoxyphenyl)-6-phenylfuro[2,3-d]-pyrimidin-4-yl]amino}hexyl-methanesulphonate and 526 mg (8.1 mmol) potassium cyanide in 20 ml DMF overnight at 80° C. After cooling, dilute with ethyl acetate and wash with water and saturated sodium chloride solution. Dry the organic phase over magnesium sulphate and concentrate by evaporation. Purify the raw product by RP-HPLC (column: Gromsil 250 mm×40 mm, 10 μm; acetonitrile/water gradient: 0-3 min 5% acetonitrile, 3-50 min 5%→98% acetonitrile, 50-55 min 98% acetonitrile). 249 mg (72% of theor.) of the title compound is obtained as a yellowish oil.
