Reaction Steps

To an ice cold, stirred suspension of (E)-2-(6-fluoro-3,3-dimethyl-1-indanylidene)acetic acid (9.0 g, 0.0409 mol) in dichloromethane (200 ml) was added oxalyl chloride (15.6 g, 0.123 mol, Aldrich). The stirring suspension was allowed to warm to 25° C. during 2 h. The resulting solution was concentrated by spin evaporation in vacuo with the addition of dichloromethane (4×75 ml) to give (E)-2-(6-fluoro-3,3-dimethyl-1-indanylidene)acetyl chloride as an uncharacterized oil. Dichloromethane (approximately 70 g) was added to dissolve this residual oil and the resulting solution was divided equally and used without other purification in Examples 15i, 16 and 17.
