Cyclopropanemethanol → 3-(Cyclopropylmethoxy)-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-indazole-5-carbaldehyde

Participants

Reaction Steps

The title compound was prepared in close analogy to the procedure described in Example 11A using 166 mg (0.372 mmol) 5-(1,3-dioxolan-2-yl)-3-iodo-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-indazole (Example 6A) and 4 ml cyclopropylmethanol (instead of ethanol). The reaction mixture was filtered, and the filtrate was purified by preparative RP-HPLC (acetonitrile/water+0.05% TFA gradient) to afford 53 mg (57% of th.) of the title compound.
