실험 절차

A mixture of the product from step (iii) (0.91 g), and 1-methyluracil (0.44 g) in acetonitrile (40 ml) was treated with boron trifluoride etherate (2.47 g) and heated at 50° C. for 4 h. The solution was treated with methanol (1 ml) and evaporated. Purification was by chromatography on a biotage silica column, using 3% methanol/0.1% 0.880 ammonia in dichloromethane as eluant to give the subtitled product as a cream powder.
