実験手順
1.69 g of 3-[(2,6-difluorobenzyl)oxy]pyridine-2-amine (Example 1A; 7.13 mmol, 1 equivalent) were initially charged in 44.4 ml of ethanol, and 425 mg of powdered molecular sieve 3 Å and 6.8 g of ethyl 2-chloro-3-cyclopropyl-3-oxopropanoate (crude product from Example 23A) were added. The reaction mixture was heated at reflux for 48 h and then concentrated under reduced pressure, and the residue was chromatographed (cyclohexane/ethyl acetate as mobile phase). The product-containing fractions were combined and concentrated under reduced pressure. The residue obtained in this manner was taken up in methanol, DMSO and water. The solid obtained was filtered off and dried under high vacuum. This gave 410 mg (15.4% of theory) of the title compound.
