合成路线图解说明:

D-19050 can be obtained in a 5-step synthesis starting from 2,6-dichloropyridine (I): Compound (I) is nitrated with HNO3/H2SO4 yielding 2,6-dichloro-3-nitropyridine (II). Subsequent reaction with ammonia and 4-fluorobenzylamine leads to 2-amino-3-nitro-6-(4-fluorobenzylamino)pyridine (IV), which is hydrogenated using Raney Nickel as catalyst to the corresponding 3-amino derivative (V). This is not isolated, but reacted with (prop-1-en-3-yl)chloroformate to give D-19050.
