A method of preparing a compound represented by Structural Formula (I):
or a pharmaceutically acceptable salt thereof, wherein the variables of Structural Formula (I) are as described in the specification and claims, comprises the step of:
a) cyclizing a compound represented by Structural Formula A:
under suitable reductive cyclisation conditions to form a compound represented by Structural Formula B:
wherein R
10
is LG
1
or —X
1
R
1
, and -LG
1
is a suitable leaving group; and
b) optionally, when R
10
of Structural Formula (B) is LG
1
, further comprising the step of replacing the -LG
1
of Structural Formula (B) with —X
1
R
1
to form the compound represented by Structural Formula (I).
一种制备结构式(I)所代表的化合物或其药学上可接受的盐的方法,其中结构式(I)的变量如说明书和权利要求所述,包括以下步骤:
a) 在适当的还原环化条件下,将结构式A所代表的化合物环化,形成结构式B所代表的化合物,其中R10是LG1或—X1R1,-LG1是适当的离去基团;
b) 可选地,在结构式(B)的R10为LG1时,进一步包括用—X1R1替换结构式(B)中的-LG1,以形成结构式(I)所代表的化合物。
