Procedure
The ester of Example 143 Step 1 (0.38 g, 1.06 mmol) was treated with Cl2 following the method of Example 103 Step 3 to give ethyl 6-chloro-7-piperidin-1-yl-2-(trifluoromethyl)-2H-chromene-3-carboxylate (0.16 g, 0.41 mmol). The product structure was consistent with 1H, 19F and 13C NMR analyses.
