Reaction Steps

A 25 mL flask was charged with (2E)-1-pyrimidin-2-ylacetone O-(1-diphenylmethylazetidin-3-yl)oxime (372 mg, 1.0 mmol; which may be prepared as described in Step 4) and 1,2-dichloroethane (8.8 mL). 1-Chloroethylchloroformate (576 μL, 5.28 mmol) was added and the reaction mixture was heated to 70° C. for 3 h. After cooling to room temperature, methanol (8.8 mL) was added and the reaction mixture was heated to 70° C. for 3 h. The reaction mixture was concentrated to dryness and the crude mixture triturated in pentane and diethyl ether to give the title compound (240 mg, 99%) as a dark solid.
