Reaction Conditions:

with hydrogenchloride;potassium dihydrogenphosphate;potassium hydroxide in water;dimethyl sulfoxide; pH=7.1-7.2 at 58 - 61; for 4 h;Enzymatic reaction;

Steps:

1a Preparation of 2-chloroadenosine (III) from 2-chloroadenine and uridine
400 g of uridine and 150 g of KH₂PO₄ were dissolved with stirring in a mixture of water (52 l) and DMSO (1.8 l) at 58-61° C.
To the resulting solution, a first portion (0.75 l) of a solution prepared from 2-chloroadenine (85 g), water (7 l), and KOH (120 g) was added.
The pH of the resulting mixture was adjusted to 7.1-7.2 with aqueous KOH solution.
