Reaction Steps

Using 4-hydroxypyrido[2,3-d]pyrimidine (150 mg, 1.0 mmol) (see J. Am. Chem. Soc., 77, 2256 (1955)), phosphorus oxychloride (1.0 ml), 2-aminoindan (270 mg, 2.0 mmol), triethylamine (1.4 ml, 10 mmol), and dry dioxane (5 ml), a similar procedure to Product ion Example 203 was carried out. The product obtained was purified by silica gel chromatography (ethyl acetate:methanol=19:1) to obtain the title compound (60 mg, 0.23 mmol) having the following physical properties:
