Participants

Reaction Steps

Following the procedure of Example 3, 2-carbomethoxyindolizine was reacted with benzyloxyacetyl chloride to give 3-benzyloxyacetyl-2-carbomethoxyindolizine (VII) Cyclization of VII with hydrazine and reaction of the resulting pyridazino[4,5-b]indolizin-1-one with POCl3 gave the corresponding chloro compound (VIII). The reaction of VII with 4-(2-pyrimidinyl)-1-piperizinyl)ethyl amine gave the title compound. Treatment with ethereal HCl in ether gave the product as the trihydrochloride salt: m.p. 140° C.
