- PROCESS FOR THE PREPARATION OF ETHYL-N-(2, 3-DICHLORO-6-NITROBENZYL) GLYCINE HYDROCHLORIDE
-
The invention relates to a process for the preparation of anagrelide, and for the preparation of intermediates for use in preparing anagrelide. The invention also relates to the inte?nediates per se, in particular compounds of formula (V) where R constitutes a suitable leaving group, which may not be hydrogen. The R group may be is selected from: (i) -SiR1 3, (ii) -CH2Ar, (iii) -COOR2, and (iv) sulfonates such as -SO2R3.

- Alkyl 5,6-dichloro-3,4-dihydro-2(1H)-iminoquinazoline-3-acetate hydrohalides
-
The known blood platelet antiaggregative agent 6,7-dichloro-1,5-dihydroimidazo[2,1-b]quinazolin-2(3H)-one is prepared in high yield via an improved process involving a novel intermediate of the Formula STR1 in which R1 is (lower)alkyl and X is bromo, chloro or iodo. Two processes for the preparation of compounds of the Formula III are disclosed, one of which involves the novel intermediate STR2
