Reaction Steps
[1-Methyl-2-(4-trifluoromethyl-phenyl)-ethyl]-carbamic acid ethyl ester (I-43c: 420 mg, 1.525 mmol) in POCl3 (4.2 mL) was refluxed with P2O5 (433 mg, 3.05 mmol) at 110° C. for 2 hours to afford the crude product. The reaction was monitored by TLC (20% ethylacetate in hexane). Purification by column chromatography on silica gel (40% ethylacetate in hexane) afforded 40 mg of the product (11.46% yield).
