Versuchsvorschrift

A solution of 2,4,6-trichloro-5-nitropyrimidine (94 mg, 0.413 mmol) in THF (5 mL) was cooled to −78° C. and treated with Et3N (110 μL, 0.757 mmol), followed by NH3 (7 N in MeOH, 50 μL, 0.344 mmol). The reaction was warmed to 0° C. Once TLC indicated complete consumption of the starting material, the crude product solution was immediately used in the reaction below (Scheme 40).
