butan-2-ylurea

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: By the procedure of Example 4, 6.96 g (60 mmol) of sec-butyl urea was reacted with 10.9 g (50 mmol) of ethyl 2-chloro-4,4,4-trifluoroacetoacetate at 140°-150° C. for 3 hours. The product was separated and then Kugelrohr distilled to yield 4.0 g of a colorless oil product (b.p.=100° C. @ 0.25 mm Hg) identified in Table I. The product was separated Kugelrohr distilled

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
