Procedure

To a mixture of the 17-allyl-14-(tert-butyl-dimethyl-silanyloxy)-1-hydroxy-12-{2-[4-(7-(tert-butyl-dimethyl-silanyloxy-carbonyl)heptanoyl-oxy)-3-methoxy-cyclohexyl]-1-methyl-vinyl}-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-aza-tricyclo[22.3.1.04,9]octacos-18-ene-2,3,10,16-tetraone prepared in Reference Production Example 1 (44 mg, 0.037 mmol) and acetonitrile (0.88 ml), 46-48% aqueous hydrogen fluoride (HF) (0.12 ml) was gently added, and this was followed by overnight stirring at room temperature. The reaction product was poured over an ethyl acetate-water mixed solution and extracted. The organic phase obtained was washed with water and saline, and dried over magnesium sulfate (MgSO4). After the MgSO4 was separated by filtration, the filtrate was concentrated under reduced pressure. The residue thus obtained was purified using a silica gel column (5% methanol (in chloroform)) to yield the desired 17-allyl-1,14-di-hydroxy-12-{2-[4-(7-carboxy-heptanoyl-oxy)-3-methoxy-cyclohexyl]-1-methyl-vinyl}-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-aza-tricyclo[22.3.1.04,9]octacos-18-ene-2,3,10,16-tetraone (14.2 mg, 40%).
