Route of Synthesis (ROS) of 3-Aminopyridine CAS 462-08-8

ConditionsYieldIn 2-methoxy-ethanol; 1,2-dichloro-benzene at 100 - 150℃; Solvent;Experimental Procedure1-2; 1-2 Example 1: Numbers 7 and 8 of Table 1Mix 2ME (2-methoxy ethanol) and o-dichlorobenzene at a ratio of 9:1 or 8:2 in a 70ml vial to prepare 12ml of solvent, and then 3.44g (0.02mol) of FAI (Formamidinium Iodide) is dissolved in the solvent. Then, add 9.22 g (0.02 mol) of PbI2 (Lead Iodide) of the same equivalent to a 70 ml glass bottle in which FAI is dissolved, and mix for 3 hours until PbI2 is dissolved. After that, the solvent is stirred in the oil bath prepared at about 100 ~ 150°C for 10 to 30 minutes until the black powder (powder) of α-FAPbI3 falls as a precipitate. However, the black precipitate formation time may vary depending on the external temperature. Thereafter, the precipitate was filtered from the solvent under reduced pressure, and the filtered precipitate was dried on a hot plate prepared at 150° C. for 10 minutes to obtain black α-FAPbI3 in a yield of 85% or 90%. The above-described method can be similarly applied to numbers 9 and 10 of Table 1.
