    摘要: 6,7-Dihydro-5H-imidazo[1,5-a]pyridin-8-one (I), is obtainable in high yields by: 1) a process which proceeds from a suitably protected C-(3-hydroxypyridin-2-yl)methylamine whose amine is converted to the formamide which is then cyclized to the imidazo[1,5-a]pyridine and hydrogenated to the 6,7-dihydro-5H-imidazo[1,5-a]pyridin-8-one, and suitably protected C-(3-hydroxypyridin-2-yl)methylamines can be prepared either in 2 steps proceeding from commercially available 3-hydroxy-2-cyanopyridine [932-35-4] or in 3 steps proceeding from commercially available 2-hydroxymethylpyridin-3-ol [14173-30-9]; 2) a process for preparing 4-hydroxy-1-(1H-imidazol-4-yl)butan-1-one, an intermediate from the synthesis of 6,7-dihydro-5H-imidazo[1,5-a]pyridin-8-one (formula I), as described in WO 2002/040484, proceeding from N,N-dimethyl-2-(trialkylsilanyl)imidazole-1-sulphonamide by lithiation and subsequent reaction with a suitably protected 4-hydroxybutyraldehyde, followed by oxidation of the secondary alcohol, acid-induced deprotection of the imidazole and deprotection of the alcohol functionality; 3) a process which proceeds from 5,6,7,8-tetrahydroimidazo[1,5-a]pyridine [38666-30-7], which is oxidized.

    摘要: A threaded connection includes first and second tubular components, each including a respective male and female end. The male and female ends each include at least one threaded zone and finish in a terminal surface. The male threaded zone includes a first portion in which a width of teeth, CWTp, increases from a value CWTpmin corresponding to a width of a tooth closest to the terminal surface of the male end to a value CWTpmax corresponding to a width of a tooth furthest from the terminal surface. A width of teeth CWTb of the female threaded zone decreases from a value CWTbmax corresponding to a width of a tooth furthest from the terminal surface of the female end to a value CWTbmin corresponding to a width of a tooth closest to the terminal surface. The threaded zones cooperate in accordance with a self-locking make-up, with CWTpmin/CWTbmax≥0.2 and CWTbmin/CWTpmax≤CWTpmin/CWTbmax.
