  We say that a class $\mathcal{B}$ of analytic functions $f$ of the form
$f(z)=\sum_{n=0}^{\infty} a_{n}z^{n}$ in the unit disk $\mathbb{D}:=\{z\in
\mathbb{C}: |z|<1\}$ satisfies a Bohr phenomenon if for the largest radius
$R_{f}<1$, the following inequality $$ \sum\limits_{n=1}^{\infty} |a_{n}z^{n}|
\leq d(f(0),\partial f(\mathbb{D}) ) $$ holds for $|z|=r\leq R_{f}$ and for all
functions $f \in \mathcal{B}$. The largest radius $R_{f}$ is called Bohr radius
for the class $\mathcal{B}$. In this article, we obtain Bohr radius for certain
subclasses of close-to-convex analytic functions. We establish the Bohr
phenomenon for certain analytic classes
$\mathcal{S}_{c}^{*}(\phi),\,\mathcal{C}_{c}(\phi),\,
\mathcal{C}_{s}^{*}(\phi),\, \mathcal{K}_{s}(\phi)$. Using Bohr phenomenon for
subordination classes \cite[Lemma 1]{bhowmik-2018}, we obtain some radius
$R_{f}$ such that Bohr phenomenon for these classes holds for $|z|=r\leq
R_{f}$. Generally, in this case $R_{f}$ need not be sharp, but we show that
under some additional conditions on $\phi$, the radius $R_{f}$ becomes sharp
bound. As a consequence of these results, we obtain several interesting
corollaries on Bohr phenomenon for the aforesaid classes.
