Step 2. To a mixture of 1-(5-phenyl-thieno[3,2-c]pyrazol-1-yl)-ethanone [3.82 g, 15.8 mmol, Intermediate (44)] and ethanol (50 mL) was added 6 N hydrochloric acid (50.0 mL, 300 mmol) in one portion and the resulting mixture heated at 70° C. After 18 hours, the reaction was cooled to ambient temperature and neutralized with 25% aqueous potassium carbonate. The mixture was diluted with water (200 mL) and aged at 0° C. for 1 hour. The resulting solid was collected, washed three times with water (50 mL), and then dried under vacuum to give 5-phenyl-1H-thieno[3,2-c]pyrazole [2.93 g, 92%, Intermediate (45)] as a beige powder. LC/MS: 201.0 (M+H), RT=3.15 minutes). Step 3. Crushed KOH (1.09 g, 6.49 mmol) was added in one portion to a stirred mixture of 5-phenyl-1H-thieno[3,2-c]pyrazole [1.30 g, 6.49 mmol, Intermediate (45)], iodine (2.47 g, 9.73 mmol), and dimethylformamide (15 mL) under nitrogen at room temperature and the dark reaction was stirred at room temperature. After 3 hours, 10% aqueous NaHSO3 (40 mL) was added with stirring. The resulting slurry was diluted with water (40 mL) and the mixture stirred at room temperature for 5 minutes. The solid was colleted by filtration, washed three times with water (20 mL) and then dried under high vacuum at 40° C. to give 3-iodo-5-phenyl-1H-thieno[3,2-c]pyrazole [1.94 g 91%, Intermediate (46)] as a tan powder.
