If I interpret your nonviable snippet you want the hairpin to start halfway
through the measure and thus 1/3 into the dotted half note. Which means your
crescendo should apply to the c’2. rather than the c’4, which means the logical
snippet would be:
\relative {
c'4 \after 4 \< \after 2.\! 2.
% or
c'4 \after 4 \< 2. <>\!
}
Note: The explicit crescendo-end (either with another \after, or by an empty
chord is required in this small snippet as without it Lilypond complains
(warning) about an unterminated crescendo and completely omits the hairpin.
Depending on where the crescendo needs to end in your actual music you may or
may not need it, but for this snippet it is required to add.
