80.9 mg was dissolved in 0.81 ml of methanol, and after ice-cooling, 13.2 mg of sodium borohydride was added, and the mixture was reacted under ice-cooling. After reacting for 3 hours and 30 minutes, 4.5 mg of sodium borohydride was added again to continue the reaction. Next, in order to decompose excess sodium borohydride, 1.5 ml of acetone was added and concentrated under reduced pressure, dissolved in chloroform, filtered with GF3, and concentrated again under reduced pressure. Dissolve the residue in 10 ml of chloroform and add 2
ml of saturated aqueous sodium sulfate solution twice.

4 g of mycaminosyl tylonolide dimethyl acetal was dissolved in 40 ml of anhydrous pyridine, and 0.68 g of dimethylaminopyridine was added thereto.
After the reaction solution was cooled with ice water, 7.2 ml of propionic anhydride was added thereto. The reaction solution was gradually warmed to room temperature and left as it was for 2 hours and 30 minutes. TLC
(Merck F254 developing solvent cyclohexane-acetone = 7:4), the starting material spot at the origin disappeared and a main product spot was found at Rf0.31. After cooling the reaction solution again with ice water, add 2 ml of water.
was added to destroy excess reagent, and after 30 minutes, this was concentrated under reduced pressure. Add 200ml of toluene to the resulting residue.
The organic layer was extracted with 100 ml of a saturated aqueous sodium bicarbonate solution three times, and the organic layer was extracted with a saturated aqueous sodium sulfate solution three times.
Washed twice with 100 ml of water, dried over anhydrous sodium sulfate, and concentrated under reduced pressure to obtain 23-deoxy-
5 g of 23-hexamethyleneimino-3,2',4'-tri-0-propionyl mycaminosyl tylonolide dimethyl acetal was obtained. (2) Subsequently, this compound was dissolved in 100 ml of methanol and reacted at 60°C overnight. TLC (Merck

28% ammonia water = 10:1:0.1)
The main product appeared at Rf0.35 and the raw material spot for this process disappeared. After concentrating the reaction solution under reduced pressure, silica gel column chromatography (Wakogel C-200 250g, developing system chloroform)

-Propionyl mycaminosyl tylonolide dimethyl acetal 2.77 g was obtained. (3) Next, add this compound to 55ml of acetonitrile.
The solution was dissolved in a mixture of 142 ml of 0.1N hydrochloric acid and allowed to stand at room temperature for 6 hours. TLC (Merck F254, developing system chloroform-
Methanol - 28% ammonia water = 10:1:0.1)
A spot appeared at Rf0.30, and the spot of the raw material disappeared. 1.2 g of sodium hydrogen carbonate was added to the reaction solution to adjust the pH to 7, and 40 ml of a saturated aqueous sodium hydrogen carbonate solution was added to adjust the pH to 8, followed by extraction with 150 ml of chloroform.
The chloroform layer is saturated with aqueous sodium sulfate solution.
After washing with 150 ml, it was dried over anhydrous sodium sulfate and concentrated under reduced pressure. This was subjected to silica gel column chromatography (30 g of Kieselgel-60, developing solvent chloroform-methanol-28% aqueous ammonia = 25:1:0.1) to obtain 2.5 g of 23-deoxy-23-hexamethyleneimino mycaminosyl tylonolide dimethyl acetal. .
