  • Patent number: 4471119
    Abstract: There is described a process for the production of a compound of formula I, ##STR1## in which R is hydrogen or alkyl Cl to 6, and R.sub.5 and R.sub.10, which may be the same or different, are each hydrogen or alkyl Cl to 6,or a pharmaceutically acceptable derivative thereof,which comprises removal of an activating group from a compound of formula II, ##STR2## or a suitable derivative thereof, in which R, R.sub.5 and R.sub.10 are as defined above, andX represents an activating group,and if desired or necessary converting the resulting compound of formula I to a pharmaceutically acceptable derivative thereof, or vice versa.There is also described a process for the production of a compound of formula II in which R is hydrogen, or a suitable derivative thereof, which comprises reaction of a compound of formula III, ##STR3## or a suitable derivative thereof, in which R.sub.5 and R.sub.10 are as defined above, with a compound of formula IV,X--N.dbd.C.dbd.O IVin which X is as defined above.
