Similar procedures have been used in preparing other 2-alkylaminoethanols and N-alkyl derivatives of l-amino-2-pro-panol, 2-amino-l-propanol, 3-amino-l-propanol, 2-amino-l-bu-tanol, and l-amino 2-methyl-2-propanol. ... [Pg.39]

Die 1-Aminierung mit O-Diphenylphosphinyl-hydroxylamin und Natriumhydrid in 1-Methyl-2-oxo-pyrrolidin ist sowohl fur wasserlosliche als auch fur wasserunlosliche Imidazole geeignet. Auch hier werden die Produkte iiblicherweise iiber die 1-Benzylidenamino-imidazole ge-reinigt. Auf diese Weise werden 1-Amino-611, l-Amino-4-nitro-611, l-Amino-2-methyl-4-ni(ro-611, l-Amino-2-methyl-61s und l-Amino-2-phenyl-imidazol678 hergestellt. [Pg.142]

Note The formula for l-amino-2-methyl-2-nitroguanidine is given in Ref 3 and it does not seem to agree with the numeration proposed by the ACS. If the formula of the last compd is right, then its name should be 1-amino-3-methyl-3-nitroguanidine... [Pg.232]

This compound cannot be prepared by reaction of ammonia with an epoxide, because in basic solution nucleophiles attack epoxides at the less hindered carbon, and therefore epoxide ring opening will give l-amino-2-methyl-2-propanol rather than 2-amino-2-methyl-l-propanol. [Pg.650]

Therefore Rufer studied an azo coupling reaction with uncharged coupling components, namely that of p-methoxybenzenediazonium ions with 1-naphthylamine and l-amino-2-methylnaphthalene, buffered to pH 7 at 25 °C. Both reactions are strongly catalyzed by sodium dodecylsulfate (up to 1100 times with l-amino-2-methyl-naphthalene) in cases where the surfactant concentration was higher than the critical micelle concentration (CMC). For the coupling reaction with 1-naphthylamine, both the o/p-ratio and the amount of the 2,4-bisphenylazo product are dependent on the sodium dodecylsulfate concentration. The formation of the 2,4-bisphenylazo com-... [Pg.25]

The practical utility of the facile addition of mercaptoacetic acid across the double bond of an azomethine has been used in the synthesis of thiazolo-triazolothiadiazin-6(7//)-one (328). Thus, 7//-3-methyl-5-triazolo[3,4-f>]thiadiazine hydrochloride (327), obtained by reacting l-amino-2-methyl-j-triazolyl-2-thione (326) with chloroacetaldehyde di-ethylacetal, reacts with mercaptoacetic acid in the presence of p-toluenesulfonic acid in boiling anhydrous benzene for 40 hr using a Dean-Stark water separator followed by basification with sodium bicarbonate to furnish 8a//,9//-3-methylthiazolo[3,2-u]-[l,3,4]triazolo(3,4-f>](1,3,4]-thiadiazin-6(7//)-one (328) (74IJC287) (Scheme 77). The absorption at 1725 cm (lactam carbonyl) in product 328 supports the cyclic structure in preference to the open-chain acid structure. [Pg.59]
