Versuchsvorschrift

Using analogous reagents and reaction conditions as described in Example 1 above, 1-(2-chloroethyl)-3-(2-chloro-pyridin-4-yl)urea (I-33a: 7.0 g, 30.042 mmol) in dry THF (40 mL) was reacted with 60% NaH (1.08 g, 45.06 mmol) in dry THF (30 mL) to afford the crude product. Purification by column chromatography on silica gel (1% methanol in DCM) afforded 5.40 g of the product (92% yield).
