合成路线1
The cyclization of methyl acetoacetate (I), 2-methoxybenzaldehyde (II) and thiourea (III) by means of HCl in refluxing ethanol gives the tetrahydropyrimidine (IV), which is finally cyclized with chloroacetic acid (V) and benzaldehyde (VI) by means of sodium acetate in a refluxing mixture of acetic acid and acetic anhydride.
