The group R2 may be an alkyl, alkenyl, cycloaliphatic, aryl or aralkyl group or a substituted group such as haloalkyl, hydroxyalkyl, halophenyl or alkoxyphenyl. Substituted amino groups of R4 may include acylamino, amino oxide, urethane, alkyl- and dialkyl-amino, amidino, acylamidino, hydrazino sulphonyl-amino and alkoxy amino groups, and derivatized carboxyl groups may include alkali metal salts, alkyl esters of the carboxyl residue, aldehydes, azides, amides or hydrazides. The free acids may be converted into salts such as the sodium, potassium or ammonium glucosamine, morpholine, diethylamine and choline salts. When R4 is a basic radical it is preferred to carry out the aralkylation with the nitro substituted indole and subsequently reduce the nitro group to the amino group. The amino group may be acylated in a further reaction.  Indolyl aliphatic acids used as starting materials are prepared by reacting an appropriately substituted phenylhydrazine with a b -keto aliphatic acid or by introducing the carboxylic acid residue into the 3-position under Mannich reaction conditions with formaldehyde-dialkyl-amine to produce a gramine and reacting this with an alkali metal cyanide and hydrolysing the nitrile.  Substituted phenyl hydrazines such as 4-methoxy -2- methylphenylhydrazine are prepared by reduction of the diazonium salt of the corresponding amine.  Ethyl a -(2, 5-dimethyl-2, 3-dihydro -3- indolyl)-acetate is prepared by reduction of the indole derivative with tin and hydrochloric acid.  U.S.A. Specification 2,825,734 is referred to.

Title: Improvements in or relating to plain bearings
Inventor: MITCHELL DAVID CONRAD
IPC: F16C33/12
Filed: 1951-12-21
Abstract: 719,090. Plain bearings. GLACIER METAL CO., Ltd. Feb. 20, 1953 [Dec. 21, 1951], No. 29994/51. Class 12(1) [Also in Group VIII] A plain bearing, bush, liner or thrust washer and so on of the kind comprising at least a bearing surface layer of porous structure, which layer comprises a metal or metals capable of forming soap by interaction with fatty acid contained in the porous structure, is characterized in that a substance containing moisture is incorporated with the fatty acid so that the substance may give out water to assist in the production of the soap. The fatty acid includes all aliphatic or aromatic acids capable of forming metal soap. for example, a mercapto-palmitic acid, stearic acid, palmitic acid. It is preferable to employ those fatty acids which are solid at temperatures below 30‹C, but liquid acids with additives may be' employed, capable of combining with the fatty acid to form a substance which does not solidify until a temperature below 30‹C has been reached. The preferred porous structure is a bronze containing 24 per cent lead, 4 per cent tin, and 72 per cent copper, to give a lead soap. In one embodiment a bush of porous lead-bronze which must not be heavily oxidized is treated to remove oil and water and then immersed under alternate partial vacuum and pressure in a saturated or nearly saturated solution of fatty acid in an organic solvent, for example 2.5 grams of stearic acid and 100 mils of alcohol at room temperature. The bush is then removed and dried to deposit the stearic acid. The bush is then immersed under partial vacuum and pressure in a saturated solution of copper sulphate in an organic solvent, for example, 1.1 grms of copper sulphate in 100 mils of alcohol, the bush then being dried to deposit the copper sulphate, the sulphate progressively releasing the water on heating of the bearing to 100‹C. Other examples provide from 5-40 per cent of a substance such as cupric chloride, calcium chlorate, potassiuin acetate and sodium formate, mixed with the fatty acid, so that if friction increases the heat rises and water is made available for making the soap. During rest periods the substance may regain moisture from the atmosphere. In a modification, the fatty acid may be combined with water and gelatine under alternate partial vacuum and pressure, the water being evaporated on heating of the bearing.
