This paper details a simple and efficient 3-component synthesis of 1-substituted 1,2,3-triazoles using a primary amine, 2,2-dimethoxyacetaldehyde and tosylhydrazide. The reaction proceeds in good to excellent yields using either aliphatic or aromatic amine substrates and is tolerant of a wide range of functional groups including electron-rich and deficient aryl groups, terminal alkynes, ketones and

N-Linked 1,2,3-triazoles have been prepared by a reaction of azides with vinyl acetate under microwave irradiation. Additionally, a microwave-assisted, two-step, one-pot procedure fromhalides involving azide substitution in diethyl ether, followed by reaction with vinyl acetate, has effectively been employed.

The present application relates to a compound of Formula (A),wherein R1 is selected from Formula (II) and Formula (III) and R2 is selected from Formula (IV), Formula (V) and Formula (VI) as IRAK4 inhibitors for use in methods of treatment of e.g. asthma and chronic obstructive pulmonary disease (COPD), cancer, inflammatory diseases, and autoinflammatory/autoimmune diseases such as e.g. systemic lupus erythematosus, rheumatoid arthritis, myositis, Sjogren's syndrome, systemic sclerosis, gout, endometriosis, atopic dermatitis and psoriasis. Preferred compounds of the present invention are e.g.: • N-(imidazo[1,2-b]pyridazin-3-yl)-1-cyclohexyl-2H-indazole-5- carboxamide, • N-(pyrazolo[1,5-a]pyrimidin-3-yl)-1-cyclohexyl-2H-indazole-5- carboxamide, • N-(imidazo[1,2-b]pyridazin-3-yl)-1-azaspiro[4.5]decan-8-yl-2H- indazole-5-carboxamide, and • N-(pyrazolo[1,5-a]pyrimidin-3-yl)-1-azaspiro[4.5]decan-8-yl-2H- indazole-5-carboxamide derivatives. An exemplary compound of the present invention is e.g. N- (imidazo[1,2-b]pyridazin-3-yl)-6-methoxy-2-((5r,8r)-1-methyl-2-oxo-1- azaspiro[4.5]decan-8-yl)-2H-indazole-5-carboxamide (Example 1): Formula (VII).
A textured metallocene polyethylene foam sheet suitable for use in a floor covering is made using a highly co-activated azodicarbonamide package which blows the metallocene polyethylene effectively. The preferred co-activators are zinc oxide and urea. The textured surface of metallocene polyethylene foam is formed by a chemical embossing process which utilizes a liquid triazole having an alkyl moiety as a foam-expansion inhibitor. The triazole is dissolved in a non-polar solvent to form the foam inhibitor. The preferred inhibitor is a hydrocarbon which may be halogenated.
