Hydrochloric Acid → (R)-2-amino-1-(3-but-2-ynyloxy-3-o-tolyl-azetidin-1-yl)-3-(4-methoxyphenyl)propan-1-one

Participants

Reaction Steps

1.7 g (3.5 mmol) of tert-butyl[(R)-2-(3-but-2-ynyloxy-3-o-tolylazetidin-1-yl)-1-(4-methoxybenzyl)-2-oxo-ethyl]carbamate are solubilised in 45 ml (135 mmol) of a 3M solution of hydrochloric acid in ethyl acetate. After stirring for 3 h at ambient temperature, the mixture is concentrated. 1.6 g of (R)-2-amino-1-(3-but-2-ynyloxy-3-o-tolylazetidin-1-yl)-3-(4-methoxyphenyl)-propan-1-one are obtained in the form of a beige solid with a quantitative yield.
