What kind of cement for a polypropylene bathroom sink drain?

I am connecting a 1-1/4 bathroom sink drain and am using an extension with a flared end (solvent weld). I tried PVC cement, and was not very surprised it didn't bond at all, even after the full cure time. Any recommendations for a better glue or a better method for joining two pieces?

Gluing drain fittings between the sink and the DWV piping in the wall is just plain wrong. Use standard "slip" fittings including a tail piece extension if needed and slip trap. The 1-1/4 inch washbasin drain uses a 1-1/4 inch slip nut and washer combination which is often included in the 1-1/2 inch trap assembly, otherwise buy the kit for a washbasin assembly.
