R 11 is hydrogen or C 1-6 alkyl;

R B is optionally substituted 5-membered monocyclic heteroaryl;

m is 1, 2, 3, or 4; and

p is 0 or 1.

2 . The compound of claim 1 , or a pharmaceutically acceptable salt thereof, wherein subscript p is 0.

3 . The compound of claim 2 , or a pharmaceutically acceptable salt thereof, wherein subscript m is 1, 2, or 3.

4 . The compound of claim 3 , or a pharmaceutically acceptable salt thereof, wherein ring A is pyridine.
