Trityl chloride → HCID 14217168, compound

Participants

Reaction Steps

Production of compound (22) was conducted in substantially the same manner as in step 1 of Example 6. That is, Gly-Phe (manufactured and sold by PEPTIDE INSTITUTE INC., Japan, 1.1 g, 5 mmol) was dissolved in a mixture of 2 ml of H2O, 2 ml of 2-propanol and 1.5 ml of diethylamine, to obtain a solution. To the obtained solution was portionwise added trityl chloride (1.8 g, 6.5 mmol), followed by stirring for one hour. To the resultant reaction mixture was added H2O, to thereby generate a precipitate. The generated precipitate was collected, washed with water and then dissolved into 5 ml of acetic acid, to thereby obtain an acidic solution. The obtained acidic solution was evaporated to dryness under reduced pressure, to thereby obtain 1.5 g of Trt-Gly-Phe.
