3-methoxypropylthiourea

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

Procedure: Sodium methoxide (0.81 g, 21.2 mmol, 1.05 eq.) was added to a solution of 3-methoxypropylthiourea (3.00 g, 20.2 mmol) in ethanol (10 mL). Ethyl cyanoacetate (2.18 mL, 20.2 mmol) in ethanol (10 mL) was added and the resulting white slurry was heated to reflux for 2.5 h. The solvent was evaporated and the remaining pale brown oil was treated with 2M acetic acid (15 mL,). The white crystals were filtered off and washed with acetic acid to give the title compound (2.10 g, 48%). the resulting white slurry was heated to reflux for 2.5 h The solvent was evaporated the remaining pale brown oil was treated with 2M acetic acid (15 mL,) The white crystals were filtered off washed with acetic acid

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