preparation example Construction

[1821] Preparation of intermediates:

[1822] Intermediate 1: (2S,4R)-1-[(2S)-2-Amino-3,3-dimethylbutyryl]-4-hydroxy-N-[(1S)-1-[4-(4 -Methyl-1,3-thiazol-5-yl)phenyl]ethyl]pyrrolidine-2-carboxamide hydrochloride

[1823]

[1824] Reagents and conditions: (a) (Boc) 2 O, NaHCO 3 , EtOAc / H 2 O; (b)(1)Pd(OAc) 2, KOAc, 90°C; (2) MeOH solution of 4NHCl; (c) (1) HATU, DIPEA, DMF; (2) LiOH, THF, H 2 O; (d) (1) intermediate compound 3, HATU, DIPEA, THF; (2) 4N HCl in MeOH

[1825] Step 1: Preparation of (S)-tert-butyl-1-(4-bromophenyl)-ethyl carbamate (2)

[1826] At 5°C, (S)-1-(4-bromophenyl)ethylamine (3.98g, 19.9mmol) and NaHCO 3 (1.24g, 14.8mmol) in H 2 To a mixture of O (10 mL) and ethyl acetate (10 mL) was added (Boc) 2 O (5.20 g, 23.8 mmol). The reaction lasted 2 hours. TLC showed the reaction was complete. The reaction mixture was filtered. The solid was collected and suspended in hexane (10 mL) and H 2 O (10 mL) for 0.5 h. The mixture was filtered, and the sol...

Embodiment

[1999] As described below, all compounds synthesized by 1 Characterization was performed by H-NMR and the purity was analyzed by LC / MS at wavelengths of 214 and 254 nM with UV detection. The purity of each compound in Tables 1-5 was over 90%. Molecular weights observed from LC / MS are given in Table 1, Table 2 and Table 3 as [M+H] + listed. The synthetic methods used to prepare the individual compounds are also listed in Tables 1-3.

[2000] All NMR experiments were recorded on a Bruker Mercury Plus 400NMR spectrometer equipped with a Bruker 400BBFO probe (at 400MHz for proton NMR) or on a Bruker Mercury Plus 300NMR spectrometer equipped with a Bruker 300BBFO probe (at 300MHz for proton NMR) . All deuterated solvents typically contain 0.03% to 0.05% v / v tetramethylsilane, which is used as a reference signal ( 1 H and 13 C are all set to δ0.00).

[2001] LC-MS analysis was performed on a SHIMADZU LC-MS machine consisting of a UFLC 20-AD system and a LCMS2020MS detector. ...

Abstract

The present disclosure relates to bifunctional compounds, which find utility as modulators of estrogen receptor (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a cereblon, Von Hippel-Lindau ligase-binding moiety, Inhibitors of Apotosis Proteins, or mouse double-minute homolog 2 ligand, which binds to the respective E3 ubiquitin ligase, and on the other end a moiety which binds the target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation / inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.
