## Abstract Alkylation of 2‐hydroxy‐4__H__‐pyrido[1,2‐__a__]pyrimidin‐4‐one (**1**) was investigated under solid–liquid phase transfer catalysis conditions (PTC), using tetrabutylammonium bromide and potassium carbonate. The reaction with alkyl halides led to the formation of various 2‐alkoxy produ
