Using a simple reaction protocol and easy product isolation steps, we successfully synthesized 18 different 1,2-dihydroquinazoline derivatives and were able to recycle the catalysts up to 8 times.

They also exhibit other pharmacological activities such as antihypertensive, anti-inflammatory, and antiviral effects. The synthesis of 1,2-dihydroquinazolines dates to the early 20th century when they were first synthesized by Pictet and Huber in 1911 by the condensation of anthranilic acid with aldehydes or ketones in the presence of strong acids. Since then, numerous methods have been developed for their synthesis, including the cyclization of o-aminobenzamides, the reaction of o-aminoaryl ketones with aldehydes or ketones, and the use of catalysts such as Lewis acids and transition metals. In recent years, the development of new synthetic methods for the efficient and selective synthesis of 1,2-dihydroquinazolines has been of great interest to synthetic chemists, particularly in the pharmaceutical industry. These methods include the use of microwave irradiation, ultrasound, and ionic liquids as green solvents. \u0000Overall, the synthesis of 1,2-dihydroquinazolines has been an active area of research, and new methods continue to be developed to improve their synthesis and properties for various applications.\u0000\u0000\u0000\u0000We easily synthesized two ionic liquids, [BMIM][OH] and [BPy][OH], with high yields.
