実験手順

2,6-Dichloro-5-methoxy-4-furan-2-yl pyrimidine (500 mg, 2.0 mmol) (see Example 5 for the preparation of 2,6-dicholor-5-methoxy-4-furan-2-yl pyrimidine) was dissolved in dry DMSO (10 mL) and heated to 60° C. This mixture was treated with a gentle stream of ammonia. After approximately 2 h, conversion was complete to about a 95:5 ratio of mono-amino isomers (having a molar weight of 225 g/mol). This mixture was cooled and diluted with water (50 mL), and the product extracted with ethyl acetate (2×50 mL). Then, the product was washed with ethyl acetate, twice with water (25 mL), and once with saturated sodium chloride (25 mL). The result was dried and concentrated. The product was purified by column chromatography using silica with a 5 to 20% ramp of ethyl acetate/hexane to give the title compound (400 mg, 89% yield). The various isomers were not separated.
