5-Amino-2-benzimidazolinone Use and Manufacturing

Methods of Manufacturing

Step: 21bSynthesis of 5-Amino-l, 3-dihydro-benzoimidazol-2-one.Procedure:Pd-C(140 mg) was added to a solution of 5-Nitro-l, 3-dihydro-benzoimidazol-2-one (1.4g, 0.0078mol) in MeOH and EtOAc, and was hydrogenated for 6hrs. The reaction was monitored by the TLC (10percent methanol in chloroform). The resulting reaction mixture was filtered through celite bed and was concentrated to afford lg (86 percent yield) of 5-Amino-l, 3- dihydro-benzoimidazol-2-one.EXAMPLE 35; [0198] This example illustrates a preparation of 5-(6-methoxy-l-oxoisoindolin-2-yl)-l/-f- benzo[]imidazol-2(3H)-one in an embodiment of the invention.; Step A: Synthesis of 5-amino-lH-benzo[
