prop-2-enylthiourea

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

Procedure: Example 1 was repeated with N-allylthiourea and 4-bromo-2-methylcrotonic acid, affording the title compound in a yield of 70%.

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

Procedure: Example 1 was repeated with -allylthiourea and 2-bromoethyl methyl ether, affording the title compound in a yield of 69%.

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

Procedure: Example 1 was repeated with N-allylthiourea and 2-chloro-N,N-dimethylacetamide, affording the title compound in a yield of 79%.

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

Procedure: The reaction described in Preparation 42 was repeated but using 20 g of allylthiourea, 37 g of ethyl bromopyruvate and 200 ml of ethanol, giving the title compound as a pale yellow powder. The reaction described in Preparation 42

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

Procedure: 2-Chloro-3-methylquinoxaline (5.359 g., 0.03 mole) was dissolved in 75 ml. of acetone, treated with Norit and filtered. The filtrate was added to a solution of 3.485 g. (0.03 mole) of allylthiourea in 50 ml. of acetone while the solution was stirred at room temperature under N2. A precipitate had formed at the end of 2 hours. Stirring was continued for 31/2 hours. The solid that was filtered off was washed with acetone, then ether and dried, to give 6.68 g. (75.6% yield) of product as a pink solid, m.p. 113°-114° C. filtered The filtrate was added to a solution of 3.485 g A precipitate had formed at the end of 2 hours 2 hours The solid that was filtered off was washed with acetone ether and dried to give 6.68 g
