Participants

Reaction Steps

1-Benzothiazol-6-yl-3-(4-chloro-pyridin-3-yl)-imidazolidin-2-one (84A: 50 mg, 0.1515 mmol) was added dropwise to a solution of sodium methoxide (0.122 g, 2.259 mmol) in 1,4-dioxane (15 mL) over a period of 5 minutes. The resulting mixture was refluxed for 10 hours. The reaction was monitored by TLC (10% MeOH in CHCl3). The reaction mixture was partitioned between ice water and ethylacetate. The organic layer was dried over Na2SO4 and concentrated. Purification by preparative HPLC afforded 16 mg of the product (31.66% yield).
