Reaction Steps
A solution at −78° C. of 1.5 mmol of the compound obtained in Step 3 in tetrahydrofuran is treated with 9 mmol of tert-butylithium (1.8M in hexane). After stirring the mixture for 1 hour, 12 mmol of dimethylformamide are added and the mixture is brought to ambient temperature. After reaction for 4 hours, the solution is hydrolysed by a saturated solution of NH4Cl and then extracted with dichloromethane. After treating the organic phase in conventional manner, chromatography of the residue on silica gel enables the expected product to be isolated.
