A Summary of the Reactions of Aldehydes with Amines.

“…158°, 129°, and 167°C.) are obtained by treating the aminobenzoic acids with formaldehyde in alcohol (7). The formation of resins was also noted, especially in the case of m-aminobenzoic acid.…”

“…at 58 mm.) is obtained (7). In acid solution, with half a mole of formaldehyde, 4,4'-diamino-2,2'-dimethyldiphenylmethane (m.p.…”

“…In the case of p-phenetidine, bis(p-ethoxyphenylamino)methane, m.p. 75°C., is formed, either in the presence or in the absence of alkali (7,144). In the presence of acid, the products include W-methyl-p-phenetidine and 3-(p-ethoxyphenyl) -6-ethoxy-3,4dihydroquinazoline (84).…”

“…84°, 73°, and 65°C.) when treated with formaldehyde and alkali in alcohol (7). Without the alkali, the trimeric methylenechlorophenylimines were obtained from m-and p-chloroanilines.…”

Hydroxymethylene Ketones. IV. Orientation in the Condensation of Methyl n-Hexyl Ketone with Methyl Formate

“…The apparatus for this work has been described. 4 Table I summarizes the information obtained on total yield and percentage of each isomer obtained from the nitration of 2-aminopyridine, 2-amino-3methylpyridine, 2-amino-4-methylpyridine, 2-amino-5-methylpyridine and 2-amino-6-methylpyridine. The nitration and separation of isomers was carried out as described in the Experimental portion of the paper.…”
