Reaction Steps

To a solution of 2,2,2-trichloroacetyl chloride (10.6 g, 6.52 mL, 58.1 mmol) in dichloromethane (15 mL) cooled to −10° C. was added a mixture of (E)-1-ethoxyprop-1-ene (5 g, 6.43 mL, 58.1 mmol) and pyridine (4.59 g, 4.7 mL, 58.1 mmol) over a period of 15 min. After the addition was complete, the mixture was stirred at RT for 16 h. The resulting precipitate was filtered and washed with dichloromethane. The filtrate was concentrated in vacuo and dried at 40° C. in high vacuum to give the product as brown semisolid (16.1 g with 80% purity, 95.8%). The crude material was used directly in the next step without any further purification.
