Abstract

1,224,619. Penicillins. BEECHAM GROUP Ltd. 12 Aug., 1969 [14 Aug., 1968], No. 38790/68. Heading C2A. Novel penicillins of the Formula I and non-toxic salts thereof, wherein R is C 1 -C 5 alkyl are prepared by reacting a 6-(α-aminohydroxyphenylacetamido) - penicillanic acid or salt thereof with a ketone of formula R-CO-CH 3 where R is as defined above. The reaction is preferably carried out in the presence of a base (e.g. triethylamine) in excess ketone. [GB1224619A]
