Reaction Steps

A mixture of the product of Example 122 Part C (1.55 g, 0.004 mole), thiourea (0.31 g, 0.004 mole), and absolute ethanol (8.0 mL) was heated at reflux for 7 hours. The cooled solution was treated with water (5.0 mL), cooled to 0°, and treated with concentrated hydrochloric acid (5.0 mL). The precipitated solid was isolated by filtration, rinsed with water and air-dried to provide the title compound (1.45 g, 86%) as a white powder, mp 190°-194°.
