Procedure

In the same manner, by acting (2'-methylallyl) chloride or bromide in the presence of a metallation agent, starting from 1-phenyl 8-chloro 1,2,4,5-tetrahydro 2,4-dioxo 3H-1,5-benzodiazepine, there is obtained 1-phenyl 5-(2'-methylallyl) 8-chloro 1,2,4,5-tetrahydro 2,4-dioxo 3H-1,5-benzodiazepine (R1 = H, R2 = Cl, R3 = ##STR20## R4 = C6H5) melting at 149°-151° C. upon recrystallisation in 50% ethanol.
