1,3-diethylthiourea

Conditions: temp:0.00; pressure:0.00; stir:

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

Procedure: To a filtered solution of 1.32 g. of 1,3-diethyl-2-thiourea in 25 ml. of acetone is added a filtered solution of 3-bromo-1,1-diphenyl-2-propanone in 25 ml. of acetone. The mixture is allowed to stand, then the solid is collected by filtration, washed with acetone and dried in vacuo, giving 3.73 g. of the desired product, m.p. 174°-176° C. (dec.). the solid is collected by filtration washed with acetone dried in vacuo giving 3.73 g

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

Procedure: Prepared by the method described in Example 1 from N,N'-diethylthiourea (1.0 g, 8 mmoles) and acetylenedicarboxylic acid (1 g, 9 mmoles). Crystallization from hexane gave the product (1.5 g), mp 148°-152° C. Prepared by the method Crystallization from hexane

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