Participants

Procedure

1.6 235 mg of 6-chloropurine, 400 mg of 2(-naphthalen-1-yloxymethyl)pyrrolidine and 0.8 ml of triethylamine are dissolved in 30 ml of 1-butanol and irradiated in the microwave at 120° C. for 6 h. After removal of the solvent in vacuo, the residue is taken up in 10 ml of methanol, the crystals which precipitate in the process are filtered off with suction and washed with methanol, giving 340 mg of colourless crystals 6-[(R)-2-(naphthalen-1-yloxymethyl)pyrrolidin-1-yl]-9H-purine (“A1”); Rt.: 1.806 min; [M+H]+346; m.p. 207-208°;
