2
CH
2
OH;
R
2
is H, Me, Et, n-Pr, i-Pr, C
1-2
fluoroalkyl, cyclopropyl or (cyclopropyl)methyl-;
and NHR
3
has the sub-formula (nhr3):
wherein R
3a
is methyl or ethyl; R
3b
is H, methyl or ethyl; R
3c
is H, methyl or ethyl,
R
3d
is H, methyl or ethyl, and R
3e
is H or methyl,
provided that: (a) R
3b
is methyl or ethyl; and/or (b) R
3c
and R
3d
are independently methyl or ethyl; and provided that: (c) when R
