Reaction Steps

The procedure described in Example 1d was followed using 5-methoxy-3-methyl-1,2-benzisoxazole (0.32 g, 1.96 mmol), 4-iodomethyl-1-piperidinecarboxylic acid, 1-(1,1-dimethylethyl) ester (0.70 g, 2.15 mmol), and 1M LDA (2.0 mL, 2.0 mmol) in dry THF (2 mL). After purification, the title compound (0.62 g, 87%) was obtained as a clear oil.
