Can the alkyl halide in the drawing area be made in one step from an alcohol, without losing starting material to unwanted extra products? If so$,$ add the alcohol

starting material to the left$-$hand side of the reaction, and the necessary reagents above or below the arrow.

If the alkyl halide can't be made in one step, or can't be made in good yield because of competing reactions or unwanted byproducts, check the box under the

drawing area.
