You can not directly draw a schematic in simulink - for that you need SimScape.
But you can represent the differential equation of the circuit.
Start from the higher order derivative, in this case di/dt from the inductor equation.
Then integrate it in order to get i.
Then "close the loop" using adders, gain block, and so on until you get di/dt from the other elements.

It is complicated to do with only the basic Simulink libraries.
Check in the Simulink library browser if you have the Simscape libraries installed.
Under "foundation library - electrical" you should find everything you need.
