Title: Novel heterocyclic compounds and process for the manufacture thereof
IPC: C07D213/86
Filed: 1953-03-06
Abstract: The invention comprises chemotherapeutically active compounds of the formula <FORM:0726230/IV (b)/1> wherein R represents a halogen atom or a hydroxy, mercapto or amino group, the hydrogen of any which may be substituted by a lower alkyl radical which may contain a hydroxy, carboxy, amino, alkylamino or dialkylamino substituent, and R1 represents a hydrogen atom or any of the R values.  They are prepared by condensing an isonicotinic acid halide with an isonicotinic acid hydrazide, the pyridine nucleus of one of the reactants containing chlorine or one of the above groups in the 2- or 2,6-positions, and, if desired, replacing the chlorine if present in the product by one or two of the above groups; or where two chlorine atoms are present, replacing one by hydrogen and, if desired, the other by one of the above groups.  In the examples:  (1) 2,6-dimethoxy-isonicotinic acid, obtained by heating sodium methoxide and 2,6-dichloronicotinic acid, is converted to the acid chloride by refluxing with thionyl chloride, and heated in pyridine with isonicotinic acid hydrazide to give 1 - (21,61 - dimethoxy - isonicotinyl) - 2-isonicotinyl-hydrazine. Similarly prepared are (2), (3) and (4), the 21,61-diethoxy, 31,61-diisopropyloxy, and 21,61-di-n-butyloxy derivatives; (5) the 21,61-dichloro-derivative is prepared (a) by reacting 2,6 - dichloro - isonicotinic acid hydrazide and isonicotinyl chloride hydrochloride in pyridine, and (b) by reacting the unsubstituted hydrazide with 2,6-dichloroisonicotinyl chloride. From this, 1-(21-chloro-61 - ethyl - mercapto - isoicotinyl) - 2 - isonicotinyl hydrazine is prepared by boiling with sodium methoxide and ethyl mercaptan; (6)-2-chloro-isonicotinic acid, prepared by heating the 2,6 - dichloro - derivative with hydrazine hydrate followed by boiling with copper sulphate solution, is converted to the acid chloride and warmed with isonicotinic acid hydrazide in pyridine to give 1-(21-chloro-isonicotinyl)-2-isoicotinyl-hydrazine; (8) (a) sodium and methanol are heated with 2,6-dichloro-isonicotinic acid to give 2-chloro-6-ethoxy-isonicotinic acid, the chloride is formed which, with isonicotinyl hydrazide, gives 1-(21-chloro-61 - ethoxy - isonicotinyl) - 2 - isonicotinylhydrazine, (b) 2-chloro-6-ethoxy-isonicotinic is hydrogenated with palladium nickel in NaOH to give 2-ethoxy-isonicotinic acid and the process is continued as in (a); (9) 1-(21-methoxyisonicotinyl) - 2 - isonicotinyl hydrazine is prepared by the method of (8) (b).  The Specification includes a large number of other radicals as examples of R and R1.

Abstract: 176,655. Poppe, P. A. Feb. 25, 1921. Spray carburettors. - The liquid-fuel level in a carburettor may be varied during running through a control lever, which moves between adjustable limiting stops set to decide the upper and lower level; the limits are adjustable to suit atmospheric changes and fuels of varying density. As shown, the level is varied by lifting the fulcra B<4> of the float levers B; the fulcra are carried on a slidable stem C pinned at E<2> to an inverted T-shaped lever E. The lever rests on a nut D with a number of transverse slots in its head. The lever has an elongated or round hole E' through which passes a pin E<6> on the stem C; a spring C<4> tends to keep the stem down. The nut forms the adjustable lower limit device, and the pin E<6> limits the lift of the stem by the lever when the control rod E<5> is adjusted. The level may be varied by raising the fuel-nozzle or by adjusting the float chamber as a whole. The clearance between the pin E<6> and the ends of the hole E<7> may be varied by an adjusting- screw.

B7 each comprising two amplifier members such as RS 1 , TS 2  and each of their amplifiers is connected via gates such as D1, 3; Dl, 4; D2, 3; D2, 4 to the succeeding bi-stable circuits. The left-hand amplifiers TS 1 , TS 3 ... are arranged to supply current, via resistors R 1 , R 2 . . . in parallel, to the resistance Ra. This resistance may be the heater for a thermistor in an adjustable cosine equalizer. Since the circuit counts in binary manner the resistances R1, R2... are arranged so that currents are provided through them in ratios 1:2:4... Forward stepping is arranged by applying blocking potential over lead z to block gates such as D1, 4; D1, 3 so that B 2  is changed over via D2, 4: D2, 3 only on TS 2  becoming conducting. In backward stepping, blocking potential is applied to lead w, so that B 2  is only changed over when TS 1  becomes conducting. Means may be provided for inhibiting the supply of pulses when the counter is saturated in either direction. Two resistances such as Ra may be provided one fed from the lefthand transistors and the other from the right hand transistors. With the use of a polarity sensitive device the arrangement may be made to step forwards or backwards according to the polarity of the input pulses.
