Reaction Conditions

Reaction Steps

A solution of diisopropylamine (13.1 mL) in THF was treated dropwise with butyl lithium (58.4 mL of 1.6M solution in hexanes) at −10° C. Then the reaction mixture was cooled to −70° C. and treated dropwise with 2-isopropyl-γ-butyrolactone (9.30 mL) keeping the speed of the addition at such a rate that the temperature of the mixture remained below −60° C. After completion of the addition, the mixture was stirred for 3 h at −70° C., then warmed-up to −40° C. and treated dropwise at this temperature with chloromethyl methyl ether (7.50 mL). After that, the mixture was allowed to slowly warm-up to room temperature and stirred at this temperature for 80 h. The solvents were removed in vacuum and the residue was redissolved in dichloromethane, then washed with a saturated aqueous solution of ammonium chloride, dried over magnesium sulfate, filtered, concentrated on a rotary evaporator and distilled in vacuum to give 7.00 g (57%) of the title compound.
