Reaction Steps
Five (5) drops of concentrated sulfuric acid were added to a mixture of 2-ethoxycarbonylcyclopentanone (31.2 g) and methylthiourea (18.0 g) and the mixture was heated at 100° C. for 2 days. The resulting precipitate was collected by filtration, rinsed with ethanol, and dried to provide the title compound as colorless powder (10.2 g).
