| Product | HCID 13934776 | HCID 13934776 | 83.4% |
Reaction Steps
A solution of 150 mg of 3-methyl-2piperazinyl-1,4-naphthoquinone in 50 ml of tetrahydrofuran was treated with a solution of 100 mg of 4-chlorophenylisocyanate in 10 ml of tetrahydrofuran. This mixture was stirred 1/2 hour, then evaporated in vacuo and the residue taken up in dichloromethane and filtered. The filtrate was evaporated and the residue recrystallized from dichloromethane/hexane, giving 200 mg of the desired product, mp 190°-192° C.
