Reaction Steps
Tetrahydrofuran (10 mL), 2,5-dimethylbenzylamine hydrochloride (0.858 g, 5.0 mmol, Example 94, Step 2), triethylamine (0.51 g, 5.0 mmol), and 3-butoxy-4-(1,1-dimethylpropylamino)-cyclobut-3-ene-1,2-dione (1,20 g, 5.0 mmol, Example 3) were stirred together at room temperature for approximately 18 hours. After removal of solvent the residue was triturated with water, with diethyl ether, and dried to give 1.31 g of a light yellow solid. Three recrystallizations of the crude product from acetonitrile provided 0.812 g of the title compound as a fluffy, white solid: mp 199°-200° C. (softens 195° C.). MS (m/z) 301 ([M+H]+). HPLC indicates a major component (>99%).
