Synthesis

3284-47-7
The general procedure for the synthesis of ethyl 3-hydroxy-3-methyl-1-tosylpyrrolidine-2-carboxylate from ethyl 3-hydroxy-3-methyl-1-tosylpyrrolidine-2-carboxylate was as follows: 3-alkylpyrrole derivatives were prepared according to the procedure described in Scheme 1. First, ethyl glycinate 5 was treated with p-toluenesulfonyl chloride (Ts-Cl) to give intermediate 6. Subsequently, intermediate 6 was reacted in the presence of 4-diethylaminobutan-2-one and potassium tert-butanolate (t-BuOK) to produce intermediate 7. Next, intermediate 7 was dehydrated with phosphorus oxychloride (POCl3) to give dihydropyrrole derivative 8. In the presence of sodium ethanolate, the dihydropyrrole derivative was synthesized by an elimination reaction the dihydropyrrole derivative 8 was converted to pyrrole derivative 9. Then, the pyrrole nitrogen was deprotonated using sodium hydride (NaH) and an alkylation reaction was carried out to obtain intermediate 10. finally, the ester group was hydrolyzed by potassium hydroxide (KOH) in aqueous solution in methanol (MeOH), followed by the use of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDCI) to convert the corresponding acid 11 into the target amide products (81), (82) and (83).
