6-Methyl-2-pyridinemethanol (cas: 1122-71-0) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.SDS of cas: 1122-71-0

Direct Catalytic Olefination of Alcohols with Sulfones was written by Srimani, Dipankar;Leitus, Gregory;Ben-David, Yehoshoa;Milstein, David. And the article was included in Angewandte Chemie, International Edition in 2014.SDS of cas: 1122-71-0 This article mentions the following:

The synthesis of the target compounds (terminal, as well as internal olefins) was achieved by a one-step olefination of alcs. with sulfones catalyzed by a ruthenium pincer complex. Furthermore, performing the reaction with di-Me sulfone under mild hydrogen pressure provides a direct route for the replacement of alc. hydroxy groups by Me groups in one step. Under optimized conditions the synthesis of the target compounds was achieved using (carbonyl)chloro[6-[(diphenylphosphino-κP)methyl]-2,2′-bipyridine-κN1,κN1′](hydro)ruthenium as a catalyst (homogeneous catalyst, pincer complex). Starting materials included benzenemethanol derivatives (benzyl alc.), naphthalenemethanol, benzeneethanol, 1,1′-sulfonylbis[methane] (di-Me sulfone), [(phenylmethyl)sulfonyl]benzene, (ethylsulfonyl)benzene, (2E)-3-phenyl-2-propen-1-ol, 6-methyl-2-pyridinemethanol (pyridine derivative) and similar compounds The title compounds thus formed included (ethenyl)benzene derivatives, (styrene manor products), 1-methoxy-4-[(1E)-2-phenylethenyl]benzene (stilbene), 4-[(1E)-2-phenylethenyl]-1,1-biphenyl (biaryl), (1E,3E)-(1,3-pentadienyl)benzene, 2-methyl-6-[(1E)-2-phenylethenyl]pyridine. (alkyl)arenes were formed in a direct reaction of alcs. with sulfone in the presence of hydrogen (gas). Products included 2-(ethyl)naphthalene, 4-ethyl-1,1′-biphenyl, 4-ethyl-1,2-dimethoxybenzene. In the experiment, the researchers used many compounds, for example, 6-Methyl-2-pyridinemethanol (cas: 1122-71-0SDS of cas: 1122-71-0).
