cyclobutyl(piperazin-1-yl)methanone

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: N-(Cyclobutylcarbonyl)piperazine (0.02 mole) and 2-chloro-4-amino-6,7-dimethoxyquinazoline (0.02 mole) are reacted according to the procedure of Example 1(a). When reaction is complete, the solvent is removed and the residue crystallized from methanolisopropanol to provide analytically pure 4-amino-2-[4-(cyclobutylcarbonyl)-1-piperazinyl]-6,7-dimethoxyquinazoline hydrochloride hydrate, m.p. 267°-268° C. (dec.)(corr.). When reaction the solvent is removed the residue crystallized from methanolisopropanol
