Reaction Steps

To a solution of 5-methyl-3-(3-phenyl-4-(trifluoromethyl)isoxazol-5-yl)-7-vinyl-4,5-dihydroisoxazolo[4,3-c]quinoline (Preparation 77F, 0.020 g, 0.047 mmol) in Dichloromethane (5 mL) at −78° C. was passed ozone from an ozone generator until the solution turned a deep blue. The reaction mixture then was purged with oxygen until the blue color disappeared, then with nitrogen for five minutes. The reaction mixture was allowed to warm to room temperature and triethylamine (5.07 μl, 0.036 mmol) was added. The reaction mixture was stirred at room temperature for fifteen minutes, and then concentrated under vacuum to give 5-methyl-3-(3-phenyl-4-(trifluoromethyl)isoxazol-5-yl)-4,5-dihydroisoxazolo[4,3-c]quinoline-7-carbaldehyde as a tan solid. (0.015 mg, 0.035 mmol, 74%). The product had an HPLC ret. time=3.61 min. (condition B). LC/MS M+1=426.1 min
