Yield:23947-60-6 82.2%

Reaction Conditions:

at 120; for 0.0111111 h;

Steps:

6
The second microreactor was thermostatted at 120°C, and the collected 233.8g guanidine solution and156g (0.9 mol) of methyl α-butylacetoacetate was pumped into the microreactor at a flow rate ratio of 1.56:1 at the same time,The residence reaction time of the materials in the microreactor is 40s. After all the reaction liquid is received, 30mL water is used for washing and phase separation.After the organic phase is distilled at -0.09MPa to recover the solvent, the content of 98.5percent is obtainedThe 2-ethylamino-5-butyl-6-methyl-4-hydroxy-pyrimidine was 174.4 g, and the yield was 82.2percent (calculated as cyanamide).
