Reaction Steps

2-Chloro-4-trifluoromethyl-pyridine (97 mg, 0.59 mmol), KOH (26.4 mg, 0.471 mmol) and 18-crown-6-ether (156 mg, 0.59 mmol) were added to a solution of 7-hydroxy-2-(4-methyl-pyridin-3-yl)-3,4-dihydro-2H-isoquinolin-1-one (35B: 100 mg, 0.393 mmol) in toluene (3 mL). The resulting mixture was heated to 110° C. for 3 hours. The reaction was monitored by TLC (50% ethylacetate in hexane). The reaction mixture was filtered and the filtrate was concentrated to afford the crude product. Purification by column chromatography on silica gel (30% ethylacetate in hexane) afforded 20 mg of the product (12.8% yield).
