We describe a simple and easy pathway to synthesize nitrosamine mass spectrometry standards in good to moderate yields. N-alkylation of Boc-protected primary or secondary amines using stable isotope labeled alkyl halides yielded the key intermediates that were deprotected, and then, the nitrosamine was formed with sodium nitrite and sodium hydrogensulfate. Special attention to safety, disposal of waste
