Tetrabutylammonium Fluoride → HCID 58868931, compound

Participants

Reaction Steps

10.4 ml (10.4 mmol) of a 1N tetrabutylammonium fluoride solution in THF are added to a solution of 2.77 g (5.22 mmol) of benzyl N-(tert-butoxycarbonyl)-3-{[tert-butyl(dimethyl)silyl]oxy}-6-nitro-L-phenylalaninate (Example 5I) in 50 ml of THF, and the mixture is stirred at RT for 30 min. The solution is then poured into ice-water and extracted several times with ethyl acetate. The organic phase is dried over magnesium sulfate and concentrated in vacuo. The crude product is dried to constant weight under high vacuum.
