Alternate synthesis of a β-3 adrenergic receptor agonist
Scott, Robert W.,Fox, Darrell E.,Wong, John W.,Burns, Michael P.
, p. 587 - 592 (2004)
Previously our group reported synthetic efforts used to synthesize kilogram quantities of the β-3 receptor agonist (R)-(4-(2-(2-(6-aminopyridin-3-yl)- 2-hydroxyethylamino)ethoxy)phenyl)-acetic acid, 1. Additional research was conducted to explore an alternate chiral route with a streamlined protecting group scheme. The alternate asymmetric process and synthetic rationale are described.
Synthesis of 2-amino-5-hydroxypyridine via demethoxylation
Cheng,Liu
, p. 1403 - 1404 (2016/04/08)
A convenient and efficient four-step synthesis of 2-amino-5-hydroxypyridine can be achieved by protective reaction of 2-amino-5-bromopyridine in the presence of 2,5-hexanedione to yield 5-bromo-2-(2,5-dimethyl-1H-pyrrol-1yl)pyridine, methoxylation with sodium methylate to give 5-methoxy-2-(2,5-dimethyl-1H-pyrrol-1yl)pyridine, deprotective reaction with hydroxylamine hydrochloride to produce 2-amino-5-methoxypyridine and demethylation with 95 % H2SO4 to afford the title compound in an overall yield of 45 %.
