Tert-Butyl 4-formyl-5-methoxy-7-methyl-1H-indole-1-carboxylate

It functions as a protected indole building block, facilitating the attachment of the piperidinyl moiety. The tert-butyl carboxylate (Boc) group allows for further functionalization, with the 4-formyl group serving as a site for coupling in the synthesis of the final drug substance. Tert-Butyl 4-formyl-5-methoxy-7-methyl-1H-indole-1-carboxylate is a key pharmaceutical intermediate, often employed to synthesize Iptacopan (a Factor B inhibitor for paroxysmal nocturnal hemoglobinuria).
