b) Preparation of intermediate 152; A solution of intermediate 151 (0.01014 mol) in THF (50 ml) was stirred under N2- flow at -78 0C and a solution of n-BuLi 2.5M (0.0305 mol) in THF (10 ml) was added dropwise. After addition, the reaction was continued for one hour at -78 C. A solution of DMF (0.02029 mol) in THF (10 ml) was added dropwise. The reaction mixture was stirred for 30 min at -78 0C. The reaction mixture was allowed to reach -30 0C, and H2O (10 ml) was added dropwise. The reaction mixture was stirred for 30 min. The organic layer was separated and filtered over silica gel (eluent: THF). The collected fractions were concentrated under reduced pressure and the residue was stirred in a mixture of 2% CH3OH and 98% DCM. The precipitate was filtered off, washed and dried under vacuo, yielding 0.85 g (42.8%) of intermediate 152.
