Reaction Conditions:
with pyridine in N,N-dimethyl-formamide at 0 - 15;
Steps:
1 Example 1
From the raw material 3,8-diamino-6-phenylphenanthridine is reacted with ethyl chloroformate to obtain Intermediate I, The reaction equation is: The reaction process is: 1) In a three-necked flask equipped with a mechanical stirrer, Adding DMF, 1 mole of 3,8-diamino-6-phenylphenanthridine was added thereto, While stirring; Followed by the addition of 2 moles of pyridine, Cooling to 0 -5 deg C; 2) 2 molar amounts of ethyl chloroformate was slowly added to the reaction system in 1, During the addition the temperature must not exceed 15 deg C, TLC traces to the end of the reaction; At this time, 3) a viscous solid was obtained, The pyridine and DMF were removed by filtration, The remaining solids are poured into the water for adequate washing; After washing, The resulting solid was dried in vacuo, To give the product intermediate I, The yield was 90%.
