The starting material was dissolved at “parameter 4” C. The appearances of reaction solution were “parameter 5” and “parameter 7” in about “parameter 6” minutes, and then the solution was heated at 110~120C for “parameter 8” hours and concentrated in room temperature. The “parameter 9” mL MeOH was added and the resulting mixture was stirred for “parameter 10” minutes. To the solution, which is “parameter 1 1” in a ice-bath, NaBH4(s) “parameter 12” was added slowly under N 2 and stirred for “parameter 13” minutes. The solution, which is “parameter 14,” was added with “parameter 15” mL H2O and extracted with “parameter 16” mL CHC13. The organic layer was added with MgS04 for drying, stirred for “parameter 17” minutes, filtered, and concentrated to obtain “parameter 18”.
