METHOD FOR PREPARING COUMARIN COMPOUNDS SUBSTITUTED BY AMIDOALKYL AT 3-POSITION, THE PRODUCTS AND RELATED INTERMEDIATES THEREOF
摘要:
The present invention relates to a method for preparing coumarin compounds substituted by amidoalkyl at 3-position, and related intermediates thereof. The method includes:
Step (A): reacting a compound of formula (VI) with a compound of formula (V) to give a compound of formula (VII)
wherein R
1
and R
2
are each independently selected from hydrogen, halogen, and —O(C
1-8
alkyl), wherein the alkyl is optionally substituted with 1 or 2 groups selected from the group consisting of halogen, C
1-8
alkyl substituted with 1-2 hydroxyl groups, —O(C
1-8
alkyl);
R
3
is -L-C(O)NR
5
R
6
, L is C
1-3
alkylene.
Compounds which directly inhibit IRE-1α activity in vitro, prodrugs, and pharmaceutically acceptable salts thereof. Such compounds and prodrugs are useful for treating diseases associated with the unfolded protein response or with regulated IRE1-dependent decay (RIDD) and can be used as single agents or in combination therapies.
