  • Process for the preparation on 2-aminomethylpyridine derivatives
    Patent number: 7608720
    Abstract: The present invention relates to a novel process for the preparation of 2-amino-methylpyridine derivatives of the formula (I), comprising reacting in a first step 2-substituted pyridine derivatives of the formula (II), with a nitroalkane of the formula (III), in the presence of a base resulting in 2-nitromethylpyridine derivatives of the formula (IV) and hydrogenating these 2-nitromethylpyridine derivatives of the formula (IV) in a second step in the presence of a catalyst and in the presence of an acid, where in the formulae n, X, Y, R1, R2 and A are as defined in the description.
    Type: Grant
    Filed: April 26, 2004
    Date of Patent: October 27, 2009

  • Process for the preparation of D(-)-penicillamine and salts thereof
    Patent number: 3960940
    Abstract: D(-)-Penicillamine and salts thereof may be prepared by reacting a 6-amino or blocked 6-amino penicillin e.g. penicillin G or penicillin V, or a salt thereof, with a hydrazine having two --NH-groups, or a salt or solvate thereof.
    Type: Grant
    Filed: August 14, 1974
    Date of Patent: June 1, 1976

  • Process for preparing cephalosporin compounds from 7-ADCA
    Patent number: 3957773
    Abstract: 7.beta.-Amino-3-methylceph-3-em-4-carboxylic acid is converted to cephalexin in high yield and relatively uncontaminated with unreacted 7.beta.-amino-3-methylceph-3-em-4-carboxylic acid if it is silylated prior to acylation with phenyl glycyl chloride hydrochloride and if the acylation reaction is conducted in dimethylformamide at low temperature in the presence of certain weak tertiary nitrogen bases.
