It's too boring to just live long life if you cannot cook some good shit for your area.
So if you want to see benzos you anyway need to get somehow chloroacetyl chloride.
The most accessible route is via monochloroacetic acid.
You also need Sulfur and TCCA or other chlorine source.
First step is to make crude S2Cl2. There are some good videos on youtube about it.
For example:
No need to bother with purifying it from SCl2 as it will be produced in later step anyway.
The second (and the last) step is to produce chloroacetyl chloride by combining all shit together and bubbling additional Cl2 via rxn mixture (with some catalytic amount of iron):
US1805162 - Preparation of aliphatic acid chlorides
This method is working, but likely you will get lower yield if you are not skilled and don't have efficient column.
