The proportion of reactants is also the key, and it must be carefully prepared according to the stoichiometric relationship and combined with the characteristics of the actual reaction.

Second, the N-methyl group is introduced. This step often requires the help of suitable methylation reagents, such as iodomethane. In an alkaline environment, the nitrogen atom on the indene derivative can undergo a nucleophilic substitution reaction with the methylation reagent. However, the strength of alkalinity has a great impact on the reaction. If the alkalinity is too strong, it may trigger the reaction of other groups; if the alkal < Br >
Third, when the key groups are introduced, the last step is a salt-forming reaction to obtain the target hydrochloride. The resulting free amine is reacted with hydrogen chloride gas or hydrochloric acid solution in an appropriate solvent. The choice of solvent is also particular, and factors such as its solubility to the reaction and the stability of the product need to be considered.

Synthesis of this compound requires careful operation at every step, and the control of the reaction conditions must be as accurate as a butcher. From the selection of raw materials, to the optimization of the reaction conditions, to the separation and purification of the product, are the key to the synthesis of this compound. Negligence in any link can lead to the failure of the synthesis.
