Reaction Steps

A 250 mL round-bottomed flask was charged under a flow of nitrogen with pyridine (50 mL) and sarcosine ethyl ester hydrochloride (25 g) and then placed in an ice bath. Propionyl chloride (14.5 mL) was added by syringe over 15 minutes. After stirring for an additional 20 minutes, the ice bath was removed and the mixture was stirred for one hour. The mixture was poured into cold water (175 mL) and extracted with diethyl ether (2×100 mL) and then ethyl acetate (3×100 mL). The combined extracts were stripped on a rotary evaporator and dried under vacuum, yielding a pale yellow liquid (23.5 g). 1H NMR (CDCl3, 500 MHz) δ4.19 (q, J=7Hz, 2 H), 4.13 (s, 2 H), 3.08 (s, 3 H), 2.82 (q, J=7 Hz, 2 H), 1.29 (t, J=7 Hz, 3 H), 1.15 (t, J=7 Hz, 3 H). GC/MS: >99% pure, m/z=173.
