Reaction Steps

Tetrahydrofuran (13 mL), 3-butoxy-4-(1,1-dimethyl-propylamino)-cyclobut-3-ene-1,2-dione (1,20 g, 5 mmol) and 2,5-dichlorobenzylamine (0.88 g, 5 mmol) were stirred together for approximately 64.5 hours. Removal of solvent and thorough trituration of the residue with diethyl ether gave 1.51 g of a light yellow solid. As purification of this material by three recrystallizations from acetonitrile was unrewarding, the recovered crude product was subjected to HPLC. The solid isolated from the appropriate fractions was recrystallized from acetonitrile to afford 0.598 g of the title compound as a white solid: mp 195°-196° C. MS (m/z) 340/342/344 (M+). HPLC indicates a major component (>99%).
