Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In a similar manner to that described in Example 25 except for the use of 2-methyldodecanoyl chloride [synthesized by chlorinating 2-methyldodecanoic acid which was synthesized by the process described in Organic Synthesis, 4,616, by the method as described in B. D. Roth. et al., Journal of Medicinal Chemistry, 35, 1609-1617 (1992)] instead of 2,2-dimethyldodecanoyl chloride, 82.5 mg of the desired compound was obtained as a white powder. synthesized was synthesized by the process described in Organic Synthesis, 4,616, by the method

Procedure: 127 mg of 2,2-dimethyldodecanoyl chloride was added to a solution of 98 mg of 8-amino-7-methoxy-4-chromanone and 0.07 ml of triethylamine in 2 ml of dichloromethane, and the mixture was stirred at room temperature for 12 hr. 15 ml of 2N hydrochloric acid was added thereto, and the mixture was extracted with ethyl acetate (25 ml×2). The extract was washed with 25 ml of brine, dried over anhydrous magnesium sulfate, filtered, concentrated and purified by silica gel column chromatography (hexane/ethyl acetate=3:2) to give 198 mg of the intended title compound. the mixture was extracted with ethyl acetate (25 ml×2) The extract was washed with 25 ml of brine dried over anhydrous magnesium sulfate filtered concentrated purified by silica gel column chromatography (hexane/ethyl acetate=3:2)
