Reaction Conditions:
with sodium methylate in methanol at 0 - 20; for 4.5 h;
Steps:
1.d
212 g Benzoylthiourea (571 mmol) were suspended in 1270 ml methanol at RT, and 155 ml 30% methanolic sodium methoxide (861 mmol, 1.5 eq.) were added over 0.75 h. The suspension was stirred for 2.75 h, cooled to 0° C. and stirred for 1 h before being filtered. The crude product was sufficiently pure to be used directly in the next step. 148.7 g (97%).
